Johnson notes that the outdoor grow season lasts from around April to October, meaning if you plant seeds now, they’d still yield flower, but not much. Since it’s late in the season, he suggests buying a large clone, which will have more branches and therefore yield more flower.
Cannabis cultivation laws vary widely state-by-state. Also, we can’t stress this enough: Growing cannabis is illegal in a lot of places, and the penalties — which include steep fines and prison time — can be much worse than possession, since growing can imply an intent to distribute. Black and brown folx need to be especially scrupulous about heeding these rules, since law enforcement targets us way more than white people for weed-related charges, even if we consume it at similar rates.
Your cannabis will be ready to harvest at around October. You’ll know they’re ready when the buds “start to get really, really swollen and packed pretty tight,” Johnson says. But it can be hard to tell if you’re a beginner. Many growers say that if you think your plant is ready to harvest, wait two weeks, since many newbies tend to harvest too early. Or, you could share a photo of your crop on a forum and ask more experienced growers to weigh in.
Whatever you do, don’t plant your clones in the ground. They’ll run rampant, and “you’ll have pounds of weed in your house,” Johnson says, recalling the trays of weed atop his kitchen table when his crop grew wild. “You don’t need the stress of plants getting out of control, growing over your fence.” If your neighbors can see them, they might complain about them, and having too many plants could get you arrested.
Before you get started
If you buy seeds from a seed bank, look for those labeled “feminized” to ensure they give rise to female plants, Johnson says. But if you’re a total newbie, he suggests buying clones, which are cuttings from a “mother” female plant, available at some dispensaries, as well as at nurseries. Not only are they easier to obtain, “they’re easier to grow. You get a clone, and you transplant it to some soil.”
Indoors, cannabis thrives best in full spectrum light similar to sunlight, so a standard incandescent bulb won’t cut it, Wylie said. He recommended starting off with an inexpensive light made for growing. Sea of Green Hydrogardens in Tempe sells various grow lights.
People can also purchase cannabis seeds on websites such as Leafly. Sundberg warned that quality seeds can be pricey. Seeds are also a gamble because only female plants flower, and there’s no guarantee how many female seeds are in a packet. Feminized seeds are genetically engineered to grow only female plants, but tend to cost more.
A clone is a cutting from a living cannabis plant, which can grow into a plant itself. The new plan has the same genetic makeup as the original plant, hence, a “clone.”
What else do I need to grow a cannabis plant?
Wylie has been cultivating cannabis since 2002, when he first started growing for patient use in California. Sundberg cultivates cannabis for personal use and offers workshops for other growers.
Wylie believes cuttings are easier than seeds for beginners., but as Proposition 207 is so new, he isn’t aware yet of any legal businesses in Arizona that sell cuttings.
Where can I buy cannabis seeds?
Phoenix Seeds & Clones also sells clones.
Wylie recommended plants should be watered when the soil is dry. Growers can test this by sticking a finger into soil about halfway between the plant and edge of the pot. If the soil is warm and dry, it’s time to water.
