How long you allow a plant to grow, or the length of time from seed germination to harvest, is one of the most significant factors determining weed yield. If you start growing seeds in March rather than May, those plants will have two extra months to get big.
This will help give you a sense of how many plants you should grow. If you’re growing indoors, you can grow one plant at a time, harvest it, and start another, keeping a continuous cycle of growing.
When growing indoors, growth duration is determined by how much space you have to work with. If you have a spacious basement or shed, you can let plants grow for months and get as big as you want before forcing them to flower. If space is tight, like in a grow tent or other small areas, you may only be able to let your plants get a few feet tall.
Note that these are estimates. When growing outdoors, plants can usually get massive because they aren’t restricted to space—it’s not uncommon to get closer to a pound a plant or more.
The amount of dried buds you harvest from a weed plant is called its yield, just like any crop, such as corn, wheat, fruit, etc. Ideally, when growing weed, you want high yields and high-quality buds. Getting both takes a little practice.

Some major factors that contribute to a weed plant’s yield include:
Some regions get rain early in the fall, so you’ll want to grow plants that are ready to harvest by the beginning of October. In tropical climates, you can practically grow weed outdoors all year round.
Temperature: 68 to 78 degrees Fahrenheit. “A tool you should always have is a little temperature gauge,” Lipton said. “They call them hygrometers. They’re cheap and tell you both the temperature and the humidity.”
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.”
Find a healthy clone.
For some people, cannabis cultivation is a hobby. Others a life-long passion. But it’s unique in its vast demographic appeal. “Everyone I know grows,” Lipton said. “There are people in their 20s doing it. I know people in their 60s. It’s a fun thing for people. You don’t have to be afraid anymore.” Here are Lipton’s tips on growing your first plant.
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.
Trigger the flowering cycle.
Even with a healthy clone, however, cultivating cannabis can be a long and arduous process — especially in tight indoor spaces. “A lot of people think growing is easy, but it’s not,” Lipton said. “You have to be really on it. Not everyone has success, obviously.”
