Cannabis plants can be either male or female. Female plants yield the plump flowers, a.k.a., “buds,” that we know and love, brimming with psychoactive compounds like tetrahydrocannabinol (THC, which gets you high), Modern Farmer explains. Male plants yield much smaller flowers, which people typically don’t consume. In other words, if you want to actually indulge in your crop, you’ll want female plants.
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.”
Before you get started
Since clones come from plants that have been grown indoors, let yours chill in a shaded area for a week before exposing them to full sun, Johnson says. “The clone hasn’t tasted sun like that, and the transplant itself will be stressful.”
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.

Medical marijuana patients 18 years and older will be able to grow up to 3 mature and 3 immature plants at home starting October 1, 2021, with a cap of 12 total plants per household. All adults over age 21 will be able to grow under the same rules starting July 1, 2023. Plants must be grown indoors and must not be visible from the street. People who choose to grow their own plants must do so in their primary residence and where individuals under 21 can not access the plants.
Can I grow cannabis at home?
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.
After harvesting the plant, the grower should hang the plant upside down to dry for 10 to 14 days, he continued. The stems should feel brittle when dried. After that, trim the leaves off the flowers and put the flowers in an airtight container, like a mason jar. While the flowers are consumable at this point, the flowers can be cured for a better quality.
Wylie said most people will likely grow indoors, in a closet or garage, for example. About 75 degrees, more or less, is an optimal temperature, he said. In a small space with stagnant air, he suggested using a fan to move air in and out. A beginner can start in a closet with a 100-watt grow light and oscillating desk fan, and it’s enough to get going, he said.
What else do I need to grow a cannabis plant?
Both Wylie and Sundberg said the key items you need to grow cannabis are nutrient-rich soil, water and light.
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.
How often should I water my plant?
He recommended adding mulch to keep the soil cool. For a pot, the bigger the better for creating a buffering zone — five gallons is a good minimum, he said. Putting the pot in another pot or putting some sort of insulation barrier around it can also prevent the pot from directly baking in the sun.
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.
