How to grow a cannabis plant for beginners

Note that “mature” plants are those in the flowering stage, when plants begin to produce buds; “immature” plants are those in the vegetative stage, before they produce buds. A “household” is defined as two or more people living at a single residence.

Growing weed indoors is more expensive because you’ll need to spend money on equipment and utilities, but you can control every aspect of the grow environment and set up an indoor grow almost anywhere. Expect to grow some killer weed—indoor is known for its potency and quality.

*Illinois and Washington are adult-use states but require a medical card to homegrow.

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.

Growing weed is super easy—it’s called “weed” for a reason—so don’t worry if you haven’t grown anything before. Our clear, easy-to-digest guide will help growers of all kinds, especially first-time ones.

Indoor vs. outdoor marijuana growing

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.

Before you get started growing, you’ll need to see if you even can grow in your state. Below is a list of states in which it is legal to grow your own marijuana at home, both states with medical and adult-use legal status. If your state does not appear on this list, it is not legal to homegrow in your state .

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.

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.”

Find a healthy clone.

While most, if not all, medical and recreational farms cultivate cannabis from seeds, guaranteeing that their plants are free from viruses, most home growers, even those with experience, typically begin with clones — essentially trimmed pieces of female cannabis plants that have been rooted in separate pots. “When most people think of cannabis — you know, what you smoke — they’re thinking about the flowers of female plants,” Lipton said. “When you grow from seeds, half of them will be males. If you’re only going to do one or two plants, you don’t want to waste your time with that stuff.” A clone sourced from a dispensary or a knowledgeable friend guarantees that the plant is female and will eventually produce bud pending proper care. “You can get up to four ounces off the right plant — if you know what you’re doing.”

Both medical and recreational dispensaries now sell female cannabis clones, which retail for about $15. Alternatively, it’s commonplace for home growers to gift clones to their friends. “When you get a clone, someone will likely give it to you in a four-inch pot. You’re skipping that whole step of having to germinate seeds. You’re already 10, 14 days ahead of the game and basically ready to plant.”

Foster the right growing environment.

After 55 to 60 days, growers begin paying close attention to their plants’ trichomes — the small, bulbous fibers that develop around the flower of the female plant. “Those trichomes will turn from clear to amber,” Lipton said. “They kind of look like red hairs. You know it’s time to harvest when about 10 to 15 percent of the trichomes turn that color.” On average, cannabis plants have a five- to seven-day window of peak harvest time.

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.

Remember, a common mistake newbie growers make is to overwater plants.

Air circulation

Plants need 18 hours of light a day when in the vegetative stage and 12 hours a day when flowering. The reduction in light from 18 to 12 hours a day is what triggers the flowering cycle—when weed plants start to grow buds.

Watering and nutrients

You can let your plants get as big as you want, and can control when they flower and when you harvest, and you can start another batch right away or whenever you want. You can grow any time of year, even straight through winter or summer, and you’ll get consistent crops each time.
