When growing outdoors, the local climate is the main determining factor of when you can put seeds in the ground. Some regions are too cold to put plants outside until May, but you can start growing plants indoors with the right setup.
However big your plant gets, you’ll likely have more flower than you know what to do with. Many people will save a certain amount of flower for smoking, and make edibles, concentrates, and other weed products with the rest of their harvest.
Many factors affect how big a plant gets, but generally speaking, if you are growing a healthy plant, you can expect these yields from one weed plant:
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.
Sudden extreme changes in temperature can affect a plant’s growth and yields, such as a sudden cold snap, which can slow a plant’s growth, or a heatwave, which can dry out a plant.
Using the above yield estimate of ¼ lb., or 112 grams, for one medium-to-large-sized indoor plant, if you smoke one gram a day, that one plant would last you 112 days, or just under four months! Two grams a day would last you just under two months, and half a gram a day—or an eighth a week—would last you eight months.

Some major factors that contribute to a weed plant’s yield include:

Zkittlez Auto is ready to harvest 8-10 weeks from germination. Every time I grow this strain the smell and bud effects are excellent
Many other breeders also produce great auto-flowering strains (Dutch Passion, FastBuds, Barney’s Farm, etc.), but the following breeders stand out for consistency.
Depending on how you set up your grow, it can take anywhere from 2 months to 6 months or more to grow a marijuana plant from a seedling to the point where the plant is ready to harvest. Some methods, such as growing hydroponically indoors, give your flexibility to get a harvested plant in as little as 2-3 months. Growing outdoors generally takes longer than growing indoors and is more dependent on when you plant your seeds and how long your growing season is.
