Once you solve the lighting, you want to figure out a plan for regulating temperature, fresh air supply, and humidity.
Your home environment is probably not comfortable for a cannabis plant in terms of temperature and humidity. So you’ll likely enclose your grow space fairly tightly to contain your warm, humid air and to keep out light as well (more on that later).
Most growers here will use a tent, a ducted fan/filter to exhaust stale air and reduce the smell, a humidifier (or dehumidifier), and a space heater or air conditioner. The necessities vary seasonally. It’s important to remember that these things will take up space in your grow.
A denser grow means that the space will generate more humidity. If you pack a closet full, the plants will put moisture into the air through a process called transpiration.
I strongly recommend starting out with 2 photosensitive plants. I’d go with a rich bagged soil in 5-10 gallon pots. I’d set three goals:
- Train both plants using low stress training to create a fairly level canopy.
- Track many data points in a journal (photographs too)
- Aim to harvest 1 ounce or dried flower per square foot.
I would avoid starting with an autoflowering plant. They have their advantages, but it’s much harder (impossible, frankly) to predict how large or small they will grow. Learning light cycle discipline is an important skill, but not a complicated one. Jump in. Go photo. You will need to create absolute dark for the dark period though. If you’re in a closet, light deprivation can be a challenge. Doubling up with an inner tent can be useful.
