Other forms in which people consume cannabis are cigarettes and cigars. Marijuana also known as cannabis can also be used in brewing coffee. Cannabis when particularly sold as a medicine is also mixed into edible food items like brownies, cookies etc.

Vaporizers have also increasingly come in demand to consume cannabis. Cannabis includes SINSEMILLA which is one of the strongest forms of marijuana.

The concentrated resin has a high dose of cannabis active ingredient, as well as includes hash oil, waxy bud and hard AMBERLIKE shatter.

The main psychoactive element present in cannabis is delta 9 TETRA-HYDRO-CANNABINOL. It contains a chemical which is found in the resin produced from the dry flowers and leaves of female cannabis plant. Led grow lights plays a quite important role in growing marijuana.

It is very important to understand that how to maintain a marijuana plant. Cannabis is one of the interesting plants to grow, but it has a short lifespan. During cannabis production you will experience the whole process starting from germination to harvest time. Within a period of 3-6 months you become a successful cannabis grower.

Grow tent or a grow space

Finding a suitable growing area to start with the cannabis plantation may take up a lot of time and delay your growing activity. Instead you can start with a small grow tent in your closet.

There are several sizes to fit your needs. The ones we choose are all reflective from inside to make the most of the light source you use. They are also thick enough to keep light out so your plants get their rest time too.

Grow tents come in all shapes and sizes. 4x8 grow tents will grow four plants comfortably.

Grow tents are covered self living artificial light system for growing cannabis and other weed plants. If you want to how to grow marijuana inside your house or in your backyard, along with having a complete control over the environmental factors like temperature, humidity and light, small grow tent is the best option to look for.

Growing marijuana indoors need a privacy to prevent it from others to see it or preventing the smell to spread out everywhere. As in some places growing marijuana is considered illegal. Then in these cases you can use a grow tent.

Keep in mind all the necessary factors while purchasing your cannabis grow tent. Different people need different sizes of weed grow tents as per their requirement, depending on how much cannabis you want to grow.

Tents have either a white or silver lining inside. They are designed in such a way that it reflects light back onto the plants. some grow tents also come with a sipper, when zipped up they are completely on self environments that will not let any light from outside, odor or potential threats to reach in and damage your plants.

As well as, they will not allow anything to go out other than the extraction equipment. A good quality grow tent kit will last for a long time. When you decide to buy a tent for yourself to start your grow activity, look for a thick canvas material, strong poles, and good-quality zippers.

There are various sizes of grow tents available in the market like 2x2, 3x3, 4x4 etc. It is completely up to you weather how big of a grow tent you want.

How to grow marijuana & set up a grow tent?

First of all we have compiled a list of best grow tent which provides you a better marijuana growing experience. You can also read our articles on small grow tent, gorilla grow tent, 4x8 grow tent. Cannabis was used in western medicine as a way to treat all kinds of different ailments about 70 years back.

But, many governments across the world have marked its production illegal, despite knowing the fact that it is one of the non toxic drugs that you can use. It does not have the addictive properties.

Like cocaine or heroin. So grow and smoke as much as you want. However, the focus of this guide is to let you know the process growing marijuana indoors as quick as possible. Plus, we have also discussed the hydroponics method of growing and growing clones from cuttings.

A brief up on how to set up a grow tent is:
  1. Tools assembly (some tents do not require any tools for its assembly)
  2. Unpack the rest of the grow tent Package
  3. Understand the ventilation setup
  4. Prepare the carbon filter
  5. Hang The Lights
Lastly, cleaning your weed tent periodically during your grow process is an essential part of growing weed. You can carry out tents cleaning by following two ways.
Sanitization- is a wipe down cleaning process. It is a part of an indoor garden’s ongoing maintenance as changing light bulbs or refilling nutrient reservoirs. Sanitization eliminates some of the most unwanted micro-organisms. Sanitization not only meanscleaning of product or antimicrobial product. A simple wipe down to remove the filth will also be counted under sanitizing.
Sterilization- is a more deep cleaning process and refers to the elimination of micro-organisms including fungi, bacteria, spores and viruses. Sterilization can be performed by using heat, filtration or chemical cleaners-the most common method for the indoor gardener being the chemical cleaners.
Some of the exclusive cheapest grow setups that we suggest for growing weed indoors.

SEED and its selection

The most important part of your setup for growing marijuana from seed is, you need to get a few seeds. The cost of seeds is around $10 or more per seed. Once you have those beautiful little seeds in hand, you require a place to germinate them.

While buying your seeds be sure that you buy seeds that have a stripe pattern on it. Black color seeds are dead and not productive. Growing marijuana from seed is an interesting procedure to follow.

Let's put some light step by step on how to grow marijuana. The first thing is to choose the right seed, or by making a clone by taking a cutting from an existing plant.

If you are beginners in the field growing, we suggest you to grow from seed. Seeds germination rate is 85% or above and the success rate for growing cloned plants is only 50%. It also requires keen observation on a plant to take cutting from.

This plant is also rich in several other chemical as well as more than 400 compounds forming CANNABINOIDS. This form of resin is highly in demand by those who consume it both recreationally or have a medicinal need.

As you all know that seeds are in sleeping position to make something productive from it, and to achieve that you have to go under a certain process known as germination. Parents plants that are in a good health can only produce healthy good quality seeds.

All the features of the plant, like the height, color, aroma or quality, all depend on the seed. Higher the quality of your seed higher will be its productivity.

If you wish produce good quality cannabis, you need good quality seeds. And your ultimate worry is how do you select a seed worth growing? While making a seed selection we suggest you to avoid pale seeds, green seeds, and soft or damaged seeds.

They are not mature and ready for germination. Cannabis seeds with a hard outer shell are only considered to be good. Basically it should look like a hard, dark brown teardrop shaped seeds, with darker stripes (these are usually INDICA seeds) or brown, black mottling is usually Sativa.

There is a big variety of seeds available in the market. But you need to choose between regular seeds that can produce male or female plants, and feminized seeds that can produce only the bud-producing female plants that you want to harvest. Feminized seeds have 5% of producing hermaphrodite plants, which produce both male and female flowers and pollinate on their own.

You can find cannabis seed in many way like if you are in USA most of them are legal. And the most inexpensive way to get a seed is by receiving them from a buddy or anyone known. This way you can keep yourself in a tight privacy without the news getting spread out.

Second way of buying seed is buying it from a dealer. You need to visit a black market, but it’s risky as far as the quality is concerned. As some of the seeds may not have the potential to fully grow and become a healthy plant.

Thirdly you can check through a seed bank. Mostly they are based out in motherland and Canada, but you may find a lot of them selling online as well which is legal. There is a risk of being caught by the authorities because the seeds are packaged discreetly. The types of cannabis available in the market are:


This variety originates from Hindu “Kush” region close to Afghanistan. Kush is really strong weed. In this area of Afghanistan, the strain developed thick coats of resin which protects them from the harsh climate. Some of the popular names given to top flavors include; Purple Haze, Granddaddy Purple and Northern Lights. The INDICA strain has a more relaxing effect with the tendency of making you want to relax on the sofa.


The SATIVA strain on the other hand has energizing effects which is why they’re often used for morning or afternoon use. This strain of cannabis is used for depression and exhaustion specially. Its growth is up to 20 feet high, it is narrow with loose branches.

3. Hybrid

The seeds of various geographical areas are cross germinated to balance marijuana with both strains. This gives the marijuana user a balance between the two so you get the best of both strains.

Soil and peat Pellets for Germination

Soil is the most essential part to consider before growing any kind of crop seed or weed seed. A good germination of seed will only take place in a goof quality of soil. Hence, below we have discussed some germination methods for carrying out a germination process along with a quality of soil to be in it.


This is a good technique of germinating marijuana or any other seed. In this method you need a cup filled with warm water. Put the seeds into the warm water. If some seeds float to the top, remove them. Then cover the cup with a lid so that the light does not reach inside. And it's expected that the seeds will germinate in 48 hours or so. Some seeds will even begin to sprout within 24 hours.

Peat pellets method

There are three different ways to germinate your weed seed, first is peat pellet germination and second soil germination. If you are beginner and new in the field of growing seeds, and must be thinking, are peat pellets or seed trays best to use for seed germination.

Seed starting peat pellets have become very popular. They are fast and easy to use for planting seeds, and they are fun to use too. They look like small soil plates, and are made from compressed peat moss.

As the name suggests, these compressed soil plates are made out of peat moss, which is a popular medium to use to grow seeds and plants. But carrying out the process of germination in peat pellets possesses some advantages as well as disadvantages.

Making Use of pellets makes the process of germination easy to get seeds to germinate. Soak the pellets in water and let them expand. Then sow the seeds in such a way that they are 1⁄2" deep inside the pellet.

Keep the pellets moist, but don't water right on top of them so they don't go out of the soil filled tray. It takes around 3 to 7 days for the seeds to sprout up. Once you seeds sprout up make sure they get necessary sufficient light when they become 3 and half weeks old.

They need 18 hours of day light and 6 hours of darkness. You can set thing by putting your light on timer, making your seed to germinate the best efficient way. And once the flowering starts you need to provide the seed with 12 hours of light for proper growth. If you don’t provide the seed right environment, the seed will just remain a seed giving no fruits.

Soil germination method

Soil germination is the most natural way of germinating a seed. You simply have to place the seed about 3 mm deep into the soil and keep the soil moist for about 7 days. The success rate of this method is about 75% to 80% in terms of getting seeds to germinate. Success rate also depends on the seed quality and making use of the best soil for cannabis germination process.

The wet paper towel method

This is another simple method for growing weed seed. In this, you just have to place the seed on a damp paper towel and fold the towel over it. The success rate of this method is around 80% to 90%, but breakages are likely to occur while transplanting.

The seedling cannot thrive in a paper towel, so transplanting is necessary. We do not suggest this method as the best way to germinate the seed as the freshly germinated seeds should not be touched, which is risky.

Hence, you should transplant it with great care.Other options for germination include propagation kits. These include Rock wool cubes and have a similar success rate as compared to the paper towel trick. You can find these kits at many garden centers.

Therefore, after the above description on various ways to germinate a weed seed we suggest soil germination method as the easiest method for a beginner to practice weed growing. As in this method transplanting will not be necessary, and your weed seed will germinate the most natural way.

Lighting, distance of light from plants and its duration

Light works as plants sustaining element during germination and it can affect the plants later in life if they do not get valuable light they require. For proper germination to take place soil, nutrient quality, and watering regimen are all adequate as well.

The stage of germination is such a delicate stage, that the lights should be placed somewhat close to the cannabis plants. Like to have placed them just 4 inches above the plants is ideal if you are using florescent lights.

After your seeds sprout out, leave them growing inside the pellet, but make sure they get sufficient light. Light cycle follows like, till they are about 3 to 1/2 weeks old, they will need 18 hours a day of light and 6 hours of darkness.

The most comfortable and easy way to control this is to place your light on a timer. When they reach about 3 to 31⁄2 weeks of age, you can give 12 hours of light a day and 12 hours of darkness. That will start the flowering stage.

Now, let's put some light on, how to provide the cannabis seed the natural light effect when growing marijuana indoor in a grow tent. There's no other way but to make use to led grow lights inside your grow tent.

These grow lights consume less electricity and produce low heat. That saves your money on electricity bills because you use less electricity for light. You can also keep a track of time, by making use of a high-quality programmable timer.

However, there are many good quality timers available at a very economical rate in the market, but they do not keep accurate time check, while growers go on vacation. Therefore, while buying a timer you should look for a light that can handle big amount of current that you'll be drawing if you use a powerful light.

We have listed below some of the best led grow lights as well timers for your reference concerning, how to grow marijuana indoors

Some of the best timers

Air circulation

Making use of grow lights create some amount of heat during the weed grow process. Whereas, cannabis likes heat up to some extent point, too much of heat can make the plants burn just like how plants get burnt in a hot sunny weather during summers. So, in order to circulate air it is important to make use of fans or by any other method that you know.

As you know that for most of the living things, fresh air is something that really matters. Similarly, plants need some quality air to survive during their growth. Therefore, opening up a window or installing a fan system in the room can help your plants with some required fresh air.

During winters or in a cool weather opting for a fan is not a good idea. Neither it is suitable to keep the window of the grow tent open for a very long time. Because, the cool air coming in from out may hamper your weed plants making it difficult for you to recover them back. There are various fans available in the market to provide your indoor cannabis product a source of artificial air circulation.

Some of the best air fans to refer before you buy one:

One of the good options is stand alone fan is the Holmes Dual Blade Twin Window Fan. It's quiet, has two speed settings, and the air flow can be reversed for exhaust. Another plus point with this fan is that its motor is water proof.

These fans let you grow weed easy.

Pots for growing process

When your seedling begins to come out of their roots from the pellet, it's time to plant it in a pot. Leave the plant inside the pellet and put it deep into fresh soil in a pot. You can sow it up to halfway up the stem.

Now, your another worry could be which kind of pots to consider to transfer the seedling in another pot. The roots of your cannabis plants should not completely become dry. Dried-out roots mean that your plants can die anytime and can never be recovered.

Roots of the weed plants also need adequate air and oxygen. Fast growth is promoted when the roots can easily breathe oxygen. A stale root portion deprived of oxygen will almost always lead to problems. It entirely kills off your plants. To ease out your job we suggest


These pots are the newest, and possibly the best way to grow. They let the plant roots breathe and drain so they do not get root rot or root-bound. These pots come in various sizes. We suggest five gallon fabric containers as a good size.

You can also choose a smaller or bigger size, depending on your requirement. But it’s mostly recommended to use a three-gallon to five-gallon pot. If you are using over 25-watts of light per square foot making use of aerated pots is necessary.

Standard Flower Pot

This is another option of a good flower pot to start your weed plantation. It's a good flower pot, that you can get almost anywhere at a very economical price. They are mostly made from plastic these days, but you can also find old-style pots which are made of terracotta.

You can get these standard flower pots along with a matching saucer that serves to hold the water that runs off below the pot.

Another important thing to note about these types of pots is that they have drainage holes at the bottom to avoid waterlogging. Because not all pots come with pre-bored holes, sometimes you will have to make holes on your own to start using the pot.

Terracotta pots are heavier than plastic pots, but it's worth growing in these pots. Terracotta pot naturally soaks up and store excess moisture and provide a cooling effect to the weed plants, which in return benefits your plant's roots during hot weather.

Air Pot

These are plastic containers that have openings on the side providing automatic air-pruning for the roots of your cannabis plant. You will have to water more often since these pots tend to dry out faster as compared to standard pots. Compared to fabric pots and grow bags, AIR POT have the advantage of having a stronger body and does not trip. These pots also come along with a saucer below to old water that runs out from the pot below.

Hempy Bucket Guide

These buckets provide a manual hydroponic system for weed plantation. The difference between the normal pots and HEMPY pots is the drainage hole isn't at the bottom, but above.

It also has a small reservoir of nutrient solution at the bottom of the HEMPY bucket. You need to fill the HEMPY bucket with a mix of PERLITE and vermiculite or use clay pebbles, and then feed the plants with hydroponic nutrients. The nutrient reservoir below lets you water the plants less frequently.

HEMPY buckets are a manual way of growing without pumps for oxygen, you need to check that the nutrient solution left in the pot should not become nil, as it could lead to growing troubles.

Soil and fertilizers

Since, your growing weed for human consumption, so don't use junk or any kind of harmful ingredient to grow your cannabis. Organic soil is considered the best soil for weed, because gives the best flavor. Black Gold is another best soil for weed which sell a 16-quart bag, OMRI-certified for organic plantation.

It has a good drainage and air space. It has earthworm castings like worm poop and other organic fertilizers in it. You don't need to add more nutrients to the soil till 3- 4 weeks. And when it’s time to make use of fertilizers again you need to keep in mind that it’s for human consumption. Try not to make use of chemicals.

Are you are new in the field of growing weed? If yes then, understand well the trying the best nutrients for your setup, which is indeed a very confusing task. There are multiple nutrient companies, and each company creates several types of nutrients for different purposes.

Another important thing is to see that your plants get the right amount of nutrients at right time. There are basically two main life stages while you grow a cannabis plant, and each stage require different nutrient. Many nutrient companies are making great product. Points you should consider while choosing a nutrient for a successful weed plantation.

  • Nutrient Ratios of different brands are different from brand to brand nutrient ratios and are said to be optimal for each stage of growth.
  • There are different combinations of chemical and organic compounds that are mixed to the same nutrient ratios, and each compound reacts differently with each other. This means you can see two nutrient bottles with the exact same NPK ratios on the bottle, but each will actually provide somewhat different levels of nutrients to your plants.
  • It is really important to match your growing medium with your nutrients. Soil nutrients are somewhat different from Hydroponic nutrients and see you getting the right kind. Coco coir is a type of hydroponics nutrient.
  • Products with a really low NPK ratio like 0.2-0.2-0.1, means that this product is some type of a supplement.It’s not a base nutrient.Providing your plant with the right NPK and micro nutrients by using base nutrients, is like providing your plant with everything it needs to grow nicely. It's good to use supplements, but sometimes using it in excess can cause unwanted reactions between nutrients and can burn your plant. So, to be on the safer side, for your first grow, only make use supplements but pick only one or two supplements that appeal to you the most.
  • Nutrient companies happily sell you supplements you don't actually need so it's up to you to check and decide which one you want. We hope now you understood the basics and ready to learn how to choose between the best cannabis nutrients for your setup.

Some common types of soil mix brands available concerning how to grow marijuana indoors are:

These brands let you grow weed easy.


Good quality water is a base to grow great cannabis plants. To understand some of the finer points about water, and how it can affect your cannabis can bring things to a new stage. Most of the people do not know how to grow weed fast and easy indoors.

Water quality is mostly neglected for cannabis growing. It can be the major reason for so many problems, including nutrients. Before you start on with the growing process ask yourself, have you checked your water quality lately?

You should consider making use of filtered water instead of direct water from a faucet. It will have few chemicals. Placing a filter on your faucet is one of the easiest ways to have pure water. We will also let you know about a few good filter which you can bring into use while the growing process.

PUR filters are considered to be better than CULLIGAN or other brands. They have a good reputation, and they alert you when it’s time to change filters. The best thing about these filters is that they fit to most of the faucets. Filter last for about for about 100 gallons.

You need to water the small plants for only once a week. Adult plants need water about once a day. People who have big farms have a drip irrigation system. You can go for smaller setup for now. Buy a watering can with a long spout which makes your watering simple.

Make sure it fits under your faucet. Look for the one that makes it easy to mix liquid fertilizer. There are certain ways to know if your plant need water, or not by looking at the leaves. If they look dull and hanging down then it signifies that it needs water. Second, if the soil feels dry and warm give your plants a water spill.

If the soil feels cool and wet wait to water your plants. You even make use to hygrometer when unable to decide whether to water your plant or not. Therefore, watering your cannabis plantation at a regular and required interval is important as well as its quality.

It should not be neglected. Many problems can stem out from water inconsistencies that can affect the cannabis plant. A part from this, plants can also suffer from over or under-watering, this can include symptoms of over or under fertilization or even heat stress.

Other required instruments

Watering can

Watering can is needed while watering your weed young plants. It makes spilling water on plants easy as it has an inbuilt fertilizer dispenser, which lets you mix various supplements to water to get spilled on the plants.

HYGRO- thermometer

HYGRO meter is used to checks soil's moisture it lets u know about the right time to water your plants.

Digital microscope

Digital ​ ​microscope​lets you look at the TRICHOMES or sticky things on the buds, to see if they are brown too during the harvest time.

Garden sheers

Sheers are needed during the cutting and trimming of leaves, so that it can be done neatly.

Odor control practices while the growing process

After your weed plants become mature start flowering for a couple of months, they will start smelling really strong. This is the time when your odor control system is required. So for this you can attach charcoal filters along with your air circulation system.

Duct work is IPower's inline Air Carbon Filter is said to be the best air filter. It can last for a year if you change the flanges after 6 months. This is the lowest-maintenance solution.

A carbon filter basically performs functions like removing impurities in the outer environment. When it comes to odor management, it can be done in various forms, such as a carbon block water filter.

Indoor growing process of cannabis requires a use of fertilizers and Supplements. Which indeed brings some benefits, but it can also lead to a foul odor. The unpleasant smell of cannabis can be really strong and can reach even outside the grow tent. This is the reason why you need a best carbon filter for grow tent.

Another specialty is that a carbon filter will help you to remove disease causing compounds from the plants. Ventilation that it provides, with which air-borne insects and plant harming bacteria can be kept away from the grow room.

This helps in building the best state of health in your plants. Carbon filters come in two main forms. The first one is a carbon filter. The second one is more versatile – a carbon filter fan combo which means it can also function as an inline and exhaust fan.

Why air purifiers are necessary in grow rooms? Because, grow rooms not fitted with air purifiers can face problems of mold or mildew, which can spoil entire crops. An air purifier for a grow room set up should be able to remove both odors and the tiny spores that create mildew on the plants. Few other ways to get rid of odor in a Grow Room.

The use of a carbon filter is the most economical and effective odor management solutions.

  • If you are growing cannabis, one of the tother best solutions is that you can consider making use of odor absorbing gels. The unwanted smell will get attached to the gel in turn, replacing it with a good smell.
  • Keep a check of leakages in the exhaust. The odor will spread out from the grow tent in case of leakages.
  • Installation of odor neutralizers can also help you in another way. If you are a marijuana grower, don't consider making use of odor neutralizers during the flowering stage as they can negatively affect the quality of the buds.


Pruning of marijuana plants is needed at the time of harvest. It helps you to produce more buds. Many indoor growers keep their plants under a check, when growing on high scale due to a lack of vertical space in their grow room.

Indoor plants don't grow as large as outdoor plants, but they need to be kept under a check as they start to grow really tall. Trimming off the top stem will also let plant create more branches and grow broad instead of becoming tall.

To get a uniform growth, cut the shoots and leaves won't really harm the plant if done in moderation. But, if you cut too many shoots and leaves it can also become hard for the plant to regrow. And you will have to wait for some time to let it grow back again.

Many cannabis growers consider this activity like a waste, but during vegetative growth, the shoots are the most important part of the plant. They can produce a high-quality smoke. Cannabis leaves can also be used in cooking and edibles items.

The other technique under which cannabis is also grown is SCR-OG(SCROGGING method). Let's put some light on this method in short. The term SCROG is an abbreviated form of Screen of Green.

In screen of green method that growers optimize your lights by bringing lower buds up to the top of the canopy. This is one of the helpful processes because a good light distribution helps produce higher yields. This method has been popular for quite some time now. It can improve the yield of your grow even with basic fluorescent lights.

Mistakes not to make when pruning your plants

Pruning is snipping of a part of your plant so that the other part of the plant become stronger with better light absorption. Pruning can't be done to any part of your plants like the large leaves; you can only trim it from certain areas.

Leaves have an extremely important part to play in your plants. They are like light panels for plants, and the buds are a lifeline. Therefore, it means that if you remove the leaves you will in a way remove a lot of the strength from your plants, as it has nutrients. 

If your plant's leaves are not receiving enough light the plant will automatically absorb all of the nutrients, leaving the leaf yellow and dead.

Another thing is that you should not do plants pruning when they are flowering. As Plants suffer from little stress and you need to wait for some time for plants to recover. It takes some time to decide where a new branch or central stem is going to grow out.

You can prune your plants at least 15 days before you switching to the growing period.You can prune during the growth period every time, except for the flowering period.

Make sure you don't prune the top to allow more light to reach down. Remember the top is always more productive than the bottom. The wise thing to do would be to prune below so that the top can produce even more.

Environmental factors responsible for growing cannabis indoors

The vegetative growth period of a cannabis plant require a complete attention to understand in detail each and every aspect of the plant growth. Neglecting any one of factors can affect your marijuana plant's ability to thrive and produce excellent bud.

Many growers carry weed growing with a nonchalance which is neither effective nor fruitful. It requires special attention of the grower to taste the fruit of the entire weed plantation. But you can always try it.

Many of those who have never had a gardening experience or never been into growing, and have developed an interest in growing cannabis certainly have become addicted to cannabis growing.


Firstly, the temperature of the plants and the grow room setup should be kept under a check. The average temperature for cannabis room should be around 75°F. Cannabis plants are extremely adaptive and will produce buds in lower or higher temperatures.

But if the temperature goes extremely down or extremely high, then the quality of your plants can be little tossed. Cannabis can survive in temperatures like 50 to 55°F, but it will not produce the most powerful bud in this condition. Keeping a cannabis plant under 75°F is best for you.

Plants grow in a better form at higher temperatures, but it’s difficult to maintain those high temperatures. You may have to at times also prevent the extra heat by watering the plants more to cool down the roots.

Lights create a problem when it comes to maintaining a consistent temperature. Led grow lights produce heat, which can give the room suffocation feel and cause the plants to dry or burn. Therefore, to skip this problem we have already mentioned various steps to be taken above in the article like making use of an air- or water cooling system.

Most grow rooms maintain their average temperature that is ideal for growing marijuana, but it is also essential to monitor the temperature on a daily basis to ensure that your plants are being taken care of properly.


Humidity normally not only occurs in the Deep South or tropical environments but, it can become humid everywhere even inside the grow rooms. Generally, about 40 to 80% relative humidity is ideal. Humidity is basically presence of the water in the air.

You can control it by making use to RH meter. Growers keep RH to keep a check on the level of humidity that it stays within an ideal range. There are also various dehumidifiers that helps in maintaining humidity levels in a grow room. But they can be quite expensive.

Presence of level of Carbon Dioxide in a indoor grow setup (CO2)

CO2 is another important ingredient that your plants need to survive. CO2 is not good for humans, but plants like cannabis use CO2 as their OXYGEN. It's basically helps the plants to breathe, but it is also important for spurring and maintaining photosynthesis.

If your grow room setup is deprived of getting enough CO2, there are obviously plenty of methods to increase CO2 in a room, but the best way is with a CO2 generator. The generators help in maintaining a steady flow of CO2 coming into the room, which the plants will easily consume.

If the grow room setup is unsafe for you to breathe, means your groom room needs a little bit of toning. Otherwise, the amount of carbon dioxide in the room is directly related to how large the plant will end up growing.

Therefore, we hope the above detailed information on indoor growing of cannabis will help you growing in the best possible way and become a successful grower.

Pest related information regarding growing cannabis indoor and its treatment

#1. How to deal indoor pest related problems

Indoor growers are not much worried about diseases or pests harming their plants. But that doesn't mean it's something to be neglected entirely.

What generally happens is, microbial diseases are negligible because the bacteria's that affect plants usually don't exist in Europe or North America, where mainly the process of indoor growing of cannabis is practiced.

Growers face nutrient issues but that is the case with plants receiving too many few nutrients. This can be improved in a number of ways like.

The unsterilized soil contains the eggs or even dead body of some common marijuana pests, and growing your marijuana in that soil is harmful. At times those eggs hatch and even bacteria re-grow. This is something really bad for indoor growers. It's very simple to sterilize your soil on your own. The only thing you have to do is heat your soil in the oven to reach an internal temperature of around 160-180F. This will kill all molds, pests, weeds, and seeds. The soil will take around 30 to 45 minutes to reach 180F to sterilize. Please keep in mind that the temperatures should not exceed more than 190F.

In case you have a big quantity of soil considers using peroxide per gallon of soil. Don't forget to use fertilizers when you've sterilized your soil.

#2. Grow company plants along with cannabis plants

Cannabis grown along with natural repellent plants is certainly a good way to keep the pests away. The THC that marijuana produces acts as a natural repellent as well in its own way. It is not always so strong that it repels all the plants.

Planting pungent plants like geraniums and marigolds also help in keeping many leaf-eating insects and worms at away. Onion plant keeps away bigger pests like a rabbit.

Below is some more companion plants having anti-bacterial qualities that you can grow along with weed are:

Basil plants: This garden has a strong scent that is perfect for keeping away trips beetles, aphids and flies. Some growers even claim that it can increase oil production and flavor.

Bean plants: If your garden lacks nitrogen, planting beans may help you cure this problem. Beans absorb nitrogen from the air while they are growing and deposit as nitrites into the soil. Marijuana plants thrive on these nitrates. So if you plant beans around they grow stronger and are protected from death due to lack of nitrogen.

Garlic: Garlic protects against pests and molds. It serves as a natural fungicide that protects cannabis plants from deadly diseases. If you do not decide to plant it next to your plants, it can also be used ina spray form as a treatment.

Marigolds: Growing marigold together with cannabis acts like a virtual fence of protection around.

Mint: Mint is again a strong-smelling companion plan. Some garden pests hate to smell mint and avoid going near it. It also covers the smell of fresh growing cannabis, so, in order to keep your grow area a secret. Make use of mint with caution, as it overruns the garden. So, its better to grow mint in a pot instead of growing it in the ground.

Peppers: Chili peppers are again wonderful ways to keep away big pests such as deer, mice, and rabbits. The chili pepper plant also has a root system that gives out a chemical that defends your cannabis plants

#5. Make a fence

Consider making a fence around your marijuana garden in case bigger animals are still being troublesome despite using urine of enemy pest. Obviously, to do thing many marijuana growers do not have this luxury as people growing on private lands can only apply this technique.

#6. Spray a repellent around the plants

Using a PERMETHERIN based repellent can keep insects away from your plants. You just need to spray on the ground about 6 feet away from the plant. Any bugs that come into contact with the PERMETHRIN will die.

#7. Use organic repellents

Growers also opt for strong organic repellents, to keep pests away from their indoor and outdoor plants. Cinnamon oil, clove oil, and coriander oil all have qualities that can safeguard your weed plants nicely by easily spraying it directly on the cannabis leaves without any fear of reaction.

Pests are really something that you need not neglect on preventing or eliminating if they somehow make a place into your grow house. These pests grow naturally. The best thing that comes in the head is prevention when it comes to pest control. 

Some of the most insidious plant pests, like mites and whiteflies, are very difficult to detect. Many houseplants are used-to to these types of pests, but it just means that they don't hurt the houseplant.

Try placing a seedling along with any houseplant and see if the seedling starts to become pale and whitish color then it means that it's infected by mites. In order to maintain safety if you are using the same tools for house plants, then avoid using the same tools for your houseplants and your marijuana.

Installing a nylon mesh on the window of your indoor grow setup can prevent pests from entering your room. Make sure that you make use of pasteurized and thoroughly sterilized soil. Pests can be destructive for your marijuana plants. If you feel intruders in your grow room, be sure to act immediately.

How to deal with cannabis plants in vegetative stage

When your plant gets the first leaves, it's understood that your plant has entered a vegetative stage. Your cannabis plants keep growing bigger gradually day by day and start getting flowers in longer nights. One quality of cannabis is that, plants grow faster under temperature around 70-85 degree C. But it should get freezing old and burning hot types.

In vegetative stage, your plants only want to grow big and strong, if you feed your plant with extra nutrients. feed your weed plants with nutrients at full strength if the plant is showing signs that it needs more nutrients, if the leaves below are turning yellow green, then pale yellow and then shedding down its a first sign of a nitrogen deficiency.

The most common type of deficiency that occurs in marijuana plants is of nitrogen, if the plants do not get enough nutrients. Make sure your weed plants are getting sufficient 18-24 hours/light a day in the vegetative stage when you are growing indoors.

If growing outdoors, try to make sure you plant gets strong and direct light for the whole day and more. After reading all above content, You have better idea now how to grow weed indoors as beginner.

How to deal with weed plants in flowering stage

This is the stage where your plants start getting buds. And it will last till the harvest time. During this stage, you will need to change to 12-12 Light Schedule, Identify Gender of Cannabis Plant, exclude the male plants.

Most strains of cannabis begin this stage once they’re getting at least 12 hours of continuous darkness at night. Auto flowering cannabis plants will start the flowering stage without a change in the lighting.

But if you are an indoor grower, you must change to 12-12 light system which means 12 hours of light and 12 hours of continuous darkness you plants need to grow properly and for more accuracy concerning the timing you can also place your lights on timer.

In case of outdoors, your weed grows naturally; start to flower when the days get short enough, usually a few months before winter. The flowering stage is such a stage where your plant goes through "puberty" and gives you an idea whether they are a boy or a girl. For regular seeds, half your plants will be female and half will be male.

That's why growers prefer to start a growing process by making a clone or buying feminized seeds – all the plants will grow into females. Cannabis growers only look for females as female plants are the only ones that make buds.

Male plants just make pollen that cannot be used for smoking. A week or two after you start following your 12-12 light schedule your marijuana plants will reveal their gender.

As female plants tend to grow white sort of hairs at the top branches joints. And such plants with bunch of white hairs will turn out to be a good weed bud, which you can smoke.

Harvesting an​​​​​​d safety measures

Indoor and outdoor marijuana harvesting is basically carried out the same way. The only difference is that you have to bring your harvest inside if growing outdoors. If the plants are on private land where you can just pull them of the ground and bring them inside house without a trouble.

Harvesting your weed yield is not an easy task to do it anytime in a day having a fear of news being spread out. So, if possible try doing this during the night or in the early morning to avoid anybody seeing you.

If you do it in front of anyone may conclude to anything and can create trouble for you. Plucking a few leaves and shoots before the actual harvest time is a wise thing to do. This is because you will at least end up with something in your hand in case your production gets noticed by an onlooker or law enforcement. Indoor growers should always taste a sample leaf before hand. The leaves at the time of vegetative growth are potent enough and will provide you a good smoke.

There can never be a right time to harvest the weed plants. Late or early anyways, plants are not as concentrated as you want it. But, if you wish to have a SINSEMILLA bud, make sure you harvest the male pants early.

As later they tend to pollinate the female flowers. Removing the male flowers early will not be of any harm in terms of yield. Mostly male plants don't produce the highest quality smoke. If you do want to pollinate your female seeds, then you should just leave the male plants in the soil so that they can flower and produce pollen.

And, this way you will be left over with seeds for next year. If you want pollinated female plants, you should not pluck them out before the seeds have become completely matured. Many growers keep a check to understand their sign of high THC production and increase in the flower growth and accordingly they pluck the female plants as well.

But, make sure you don’t pull the plants early, as seeds will not be much active and won't germinate for next season. You can also check by opening up and see if they have attained a brown color associated with maturity.

Therefore, we hope the above detailed information on how to harvest your cannabis plant will help you in the best way to produce best quality cannabis yield.

Activities to perform after harvesting "cannabis"

After you have finally harvested your weed plants, the first thing that you should consider doing is cut the fan leaves from the plant. It is because they are less potent than the colas and they don't provide any cure as well as the other parts of the plant.

But, you can also make use of them. The fan leaves are known to have a very high concentration of THC, especially after they have just been plucked from the plant.

Once you have done that you can proceed to grading and manicuring the plants.

Grading- involves separating the plants from particular sex, strain, and anatomical part.

Manicuring- involves taking out extra leaves from around the colas so that the plants become dry easily. After you are done grading and manicuring your plants neatly, you can proceed towards curing them.

Curing- involves bringing out the best flavor and tone. But, make sure you do it correctly as it can reduce the level of THC present in leaves by following a wrong procedure. SINSEMILLA buds usually don’t need to be cured as they are themself enough effective.

Types of curing and its importance

Air curing- A very common way to cure a plant is by air, which involves hanging the plants upside in an un-ventilated room. The entire curing process might take around six weeks to complete.

If your days are wet days or the room temperature isn't remaining near 90°F, then you can risk your plants from developing mold, which is something you don't want to happen. 

So, to prevent this from happening make use of room heaters or other means to maintain the room temperature during the curing process.

Flue curing- process involves curing by adding an extra force that helps to heat the plants fast. Planting the plants in a water-tight box that you can later then place into a pool of water is another way. E.g. tank filled with water. Then, heat that pool of water to about 90°F consistently.When the plants become pale, turn the heat up to about 100°F.

When the entire green color has gone out of the plants, turn the heat up to 115°F. This process will also dry the plants, but make sure to turn the heat down as they start to dry; otherwise, they can end up getting burnt. This process takes about a week to complete.

Sweat curing- is An Colombian method of curing the plants in about 5 days. This process involves stacking branches and colas about 1.5 feet high and 2 square feet minimum. Under this process the microbial force makes the plants lose its green, which is similar to a fermentation process.

The minute plants tend to shed its color you should remove the plants each day, to avoid rot. Make use of paper towels, cotton sheets, or rags in between each of the plants. The rags will absorb all the extra moisture and promote the curing process.


This is another activity that you need to carry out after harvesting. Drying is a necessary process if you want to store your bud for later use. It lesser the chances of mold occurrence, ensuring that it last long. Mainly growers follow a slow drying method that involves hanging the plants upside down to let them dry out in natural air.

This usually takes about two weeks to complete. Of course, they will also start to cure a little bit during this process reducing the effectiveness of the plant somewhat.If you wish to dry out plants faster bring in use of oven, microwave and skillet.

And, in case you want to test your smoke early, it lets you taste soon after harvesting.  Do not dry your entire harvest using one of these fast-drying methods. Instead, it's better to dry the plants using a heater to promote the slower drying process. Make sure you don’t lease your cannabis in the oven or skillet for a very long time. It’s recommended to keep it for only 10 min under a 150-200 degree F. Or, you will end up spoiling it entirely. 


Storage is another after harvest activity. While storing your buds, make sure you store them in such a way that they last longer, until the next harvest. It’s recommended to store dried bud in a dark glass container and then put that container in the refrigerator. Light and heat are two of the major things that reduce the potency of the bud. Hence, keeping the storage area dark and cold will let you enjoy your smoke well later for a long time.

Avoid storing your entire harvest in one place, as it can lead to spoilage. If even one plant remains moist you will end up spoiling all the plants. That’s why it is important to porting your harvest so that they keep in good condition. With this, you can make yourself ready for your next year's plantation. And, here we come to an end discussing the post-harvesting activities you need to follow.
