Although you’ll be controlling the climate inside the grow space, climate outside the grow space will affect your plants. If the environment outside your grow space is very warm or humid, you’ll have issues controlling your grow space. Choose a cool, dry area with ready access to fresh air from outside.
How to set up an indoor grow room
Humidity is the amount of water vapor in the air. Here are some ways to control it in your marijuana grow room:
Soil and other media for growing weed indoors
Weed plants need different amounts of light during their vegetative and flowering stages. You don’t have to worry about this in an outdoor setting—the sun and the season dictate this—but when growing indoors, you will be controlling it.
You might be surprised which states don’t allow homegrowing—only five medical states and one medical territory allow homegrowing at all, and some adult-use states require a medical card.
These are all great resources but not all growers want to put in that amount of time and effort to get a ton of weed—some growers just want to have fun, grow a little weed, and smoke something they grew themselves.
Quick overview of the basics of growing marijuana
Enjoy, have fun, and learn a tip or two—growing weed is therapeutic and relaxing, and there’s nothing better than smoking weed you’ve grown yourself.

After you’ve planted your seeds or rooted your clones, it’s time to get them growing. Lower your reflector so that it’s closer to the plants rather than making them stretch to reach for light. Raise the lighting system as your plants grow. Set your light timer to be on for 18 hours per day and off for 6 hours. During this vegetative stage, the plant will grow leaves and branches but no flowers (unless it’s an auto-flowering plant).
Pruning For Higher Yield
Always use opaque jars (ones you can’t see inside) and place them in a cool dark place. Open up the jars to determine the level of moisture and leave them open if there’s any condensation forming on the inside of the glass. Slowly but surely, if you open and close the jars once or twice a day, the moist air will be replenished by dry air and the water that’s stuck in the middle of your bud will work its way to the outside and then out into the air altogether. After three weeks to a month or so curing, your buds should burn and taste perfectly.
