Things you need to grow cannabis

If you’re going to be growing cannabis in a 1.2×1.2x2m grow tent, you’ll need to use this equation:

We’re going to have a quick look through the items we mentioned earlier on our shopping list so that you can figure out for your own which models work best for you and which ones you don’t need.

Lamp strength:

In order to calculate the inline fan strength you’ll need to calculate a fourth of your extraction strength. So, if you have a 1.2×1.2x2m grow tent and a 600w lamp, you’ll need a 468m3/h extractor. So, for your inline fan you’ll need to calculate 468/4 which is 117m3/h – this is the type of intake that you’ll need.

The extraction fan may break due to overexertion and your plants may get sick due to breathing old, stale air – you may even have some problems yourself, as the smell will begin to build up and depending on the legality of your situation, the police may get involved. Remember that your odor filter should always be slightly stronger than your extraction fan when it comes to m 3 /h.

Materials needed to grow cannabis indoors | Step by Step

HPS lighting:

The flowering stage will always take about eight weeks—some strains take seven, some nine, some even more, it depends on the strain.

If your space is too humid, you may need to invest in a dehumidifier—also known as “dehueys.” However, keep in mind that while dehueys will reduce humidity, they typically increase temperature—you may need more fans or an AC when adding a dehumidifier.

These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.

Odor becomes much more difficult to manage in the final six weeks of a marijuana plant’s life, when trichomes and terpene production ramps up. You can also get odor-absorbing gels, which replace weed smells with other scents. Keep in mind that odor gels don’t eliminate odors, but simply mask them.

Without proper airflow, a grow space can experience rapid changes in humidity or develop pockets of CO2 depletion, neither of which are good for plant growth. CO2 depletion can lead to nutrient lockout, and areas of high humidity are prone to pest infestation, mold, or mildew.

For the most part, weed prefers these temps at each growth stage for optimal health:

These are quickly becoming the standard. Roots in fabric pots grow to the outer edges and attempt to bypass the porous fabric wall but are cut back, allowing new growth to occur. This process, called “air pruning,” results in a denser root composition which promotes healthy growth and development.

Dehumidifiers and ACs

As much fun as growing marijuana indoors is, having a home that perpetually smells like fresh weed can be a serious inconvenience, if not to you than possibly your neighbors. Although weed odor from a small indoor grow in a closet is much easier to manage than a large grow with several flowering plants, both can produce pesky odors that will permeate an entire home if left unattended.

You’ll likely yield about the same amount of weed in both cases, but more harvests mean you’ll have fresh weed to smoke more often and have more opportunities to grow different strains. But more harvests also means more work in cleaning up the space between harvests, trimming, etc.

Highly Recommended For Indoor Marijuana Grow

Your municipality has water quality info. You want to make sure your water contains fewer than 400 ppm of mineral content and no chlorine. You could also get a TDS meter to test this yourself, but these are not always reliable.

Water

If you are thinking about fluorescent lights, they may make sense for a very small grow of a plant or two. Anything larger than that and you would need too many bulbs.
