The plants can attract unappetizing blights like spider mites, fungus gnats, powdery mildew and grey mold, also called bud rot. And the odor can annoy neighbors. The most vocal opponents of home growing may be the Quebec government which has said it will not allow home grow immediately, as part of an effort to legalize at its own pace.
As legalization spreads, more cannabis enthusiasts are naturally going to want to try cultivation for themselves. The 2018 National Gardening Survey found 15% of US households would grow marijuana at home if it was legal. But, along with edibles, home growing is generally among the most contentious topics within the legalization debate.
How to grow your own weed
But home growing has its pleasures. Like tomatoes or carrots, growing one’s own cannabis is cheaper than buying it, and a chance to learn something.
For now, one place which has accepted home grow is Vermont. Of the nine US states which have fully legalized, Vermont is the only one not to allow a commercial industry. Instead, the state will allow possession and home growing, up to six plants, including two flowered females.
Marijuana growing can be relatively straightforward or “as complicated as you want to make it”, Graf said. Like so many aspects of cannabis, this is a culture advanced largely by solitary men, deeply invested in their competitive world.
To understand the flowering cycle, it’s important to remember that cannabis is a plant. And, like most plants, it follows the seasons. To trigger flowering — which will take 55 to 60 days to complete — growers reduce the time plants spend exposed to the light source from 18 hours to 12. “You’re basically telling your plant it’s mid-September,” Lipton said.
To harvest, many growers begin by removing the leaves of the cannabis plant with trim scissors, followed by the buds (using pruners). “We call this bucking,” Lipton said. “Gloves are also extremely important for sanitation reasons as well as to keep your hands from becoming sticky with the resin from the plant.”
Space: 3 x 3 x 5 feet, minimum. “The bigger the space, the better. With all the lights, closets get hot,” Lipton said. That said, closets help growers control light pollution when the plant is in its flowering cycle — one of the main reasons home growers favor them over larger spaces, such as living rooms. “If you have a spare bedroom, or a basement even, you can just use that and close the door,” Lipton said.
Trigger the flowering cycle.
Even in our most progressive states, however, the law is far from simple. “In Colorado, it’s now county-specific,” Lipton said. “When the amendment first passed, they said you could grow six plants per person. But now, certain counties and municipalities have come out and said it’s just six per house — there’s no combining plant counts. That means you can have three vegetating and three flowering at any given time.”

Before someone even begins to consider the genetics of their preferred strain, they should first ensure that their apartment is cannabis-friendly. There are five main factors to consider: space, temperature, humidity, the pH of water, and the amount of light.
Harvest and cure.
Light: 2,200k. “For a closet set up, I would recommend a 175-watt HPS light,” Lipton said. “Some people try to use fluorescent lighting, but I wouldn’t recommend that. You’re just not going to get a very good outcome. Nowadays, HPS lights can just go right into your home outlet, and you’d just need a timer [to set the intervals]. Position the light directly overhead. They can be pretty powerful, so you’re going to want it at least two feet from the top of the canopy [to prevent the plant from overheating].”
Sticking to that schedule is key, he added. “Say you’re at day 30 of the flowering cycle and you come into that closet when it’s supposed to be dark and turn a bunch of lights on. You’re going to throw the whole cycle off and that’s the end of that. It only takes 10 seconds.”
