[ Soil to Oil ] Guide to Growing Indoor Cannabis - Air: Temperature, Composition, and Motion

in #cannabislast year

Only these 4 ingredients are required by cannabis plants: Water, air, light, and soil. The air in our garden DOES impact growth - via factors such as temperature, gas composition, and motion (airflow). Here's how I ensure my plants get the right air they need for optimal health!

Temperature

Since we're dealing with indoor gardens in the Soil to Oil series, temperature fluctuations and extremes aren't much of an issue. My garden tends to be one corner of my livingroom. It's always about 22oC in here (room temperature). For most strains, this is great, and if you're growing at home you probably won't have to think again about this topic!

(If you had a larger indoor setup with multiple large lights you'd need additional temperature considerations such as venting, fans, and possibly even cooling.)

If your garden is against an outside wall, you may experience seasonal temperature fluctuations. Adjusting temperature controls, increasing airflow (see below), or using a physical barrier between your garden and the outside wall will help.

Cannabis plants don't mind the air temperature dropping a little at night (that's normal in nature), but at no point should it be colder than 12oC. Adult plants can handle warmer temperatures better than most people, so as long as they're properly watered, your plants won't mind if it's warm in your place.


(My recently-topped plants are recovering well, now with 2 'heads'.)

Composition

The gasses that make up your air obviously have a major impact on the health of your plants! They require a steady supply of CO2 (and not too much O2), which combines with water and light to form sugar for powering other processes. That's pretty easy to provide, since regular room air has plenty of CO2 - we're breathing out plant food! (Sophisticated growers often use techniques to increase the CO2 level in their controlled garden environments.)

The only other thing to mention here is the moisture content of the air (humidity). Contrary to many growers' beliefs, cannabis doesn't require a humid environment. In fact, humidity usually leads to issues like mold growth. Unless your local climate (and house) is exceedingly dry, you'll never need to humidify your air or mist your plants.

Motion

The movement of your garden's air is vital, and something you can control to improve your plant health.

Benefits to better airflow include increased gas exchange, reduced chance of mold, stronger stalks, and prevention of hot or cold spots within the garden. Fans, vents, and windows are the most common and cheapest ways to do this at home.

Another consideration for airflow is space between (and around) plants. Lights too close, walls too close, or even other plants too close can limit a plant's airflow, and therefore growth rate. Provide a bit of clearance around your plants.

It seems simple, but air is 1 of the 4 ingredients required by plants, and refining its temperature, composition, and flow will improve your garden.


Soil to Oil

This is part of my 'Soil to Oil' series, which is following my 4th crop grown fully on the Steem blockchain. The first posts are here, here, and here. The series intends to help intermediate gardeners adapt their skills to producing high quality clean organic cannabis, in their living room, for essentially no financial cost. If you've grown tomatoes, fruit, or flowers, you won't have trouble using what you know to succeed with cannabis. This guide isn't intended for brand new gardeners, but I encourage them to follow along and start developing their green thumbs. The MKUltra and Steem OG crop will be grown, harvested, and the oil will be extracted for medical use.

These natural and inexpensive methods can ensure the best possible air conditions for our plants. Small indoor gardens like this make managing temperature and airflow fairly uncomplicated.

40-50% humidity is ideal for flowering. There is a trick if your able to control humidity, is to drop the humidity below 40% the last 2 weeks of flower. This increases trichome production. I cant wait till i have the proper setup, so I can do this. Added co2 is really only needed for growers with high wattage HPS lights. I see so many growers using all these products to add extra c02, but it is just a waste.

Yeah, CO2 is definitely only something to mess with if you've already maximized every other factor, especially light!

If you wanted a picture of air, I could've lent you some. I got a bag of it with an Amazon shipment, but I threw it in the garbage.

Imagine, putting manufactured plastic bags of processed air into landfills?!

You wouldn't think there's much to say about air, but there is (when it comes to cannabis gardening). No proper grow guide would be complete without mentioning it!
