Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.
When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.
We can’t stress enough that the timeframes in the above graphic are ranges of time for the Northern Hemisphere. You’ll need to adjust them based on your specific region and local weather and climate.
Marijuana light cycle: 16 hours a day
The Spring Equinox is a good reminder that it’s time to kick off the outdoor growing process and start germinating your seeds.
What are a weed plant’s growth stages?
Seed germination length: 3-10 days
Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.
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.
These factors have the greatest impact on total time from seed to harvest:

Once your plant is harvested, there is a drying and curing process that takes about a minimum of two weeks before your buds are “ready” for smoking. If you aren’t a smoker and plan on turning plants into edibles or concentrates, you should still dry your buds but typically you don’t need to cure your buds.
Auto-flowering plants tend to stay small since they go from seed to harvest in under 3 months. These auto-flowering plants produced about 7 ounces.
How to grow marijuana as quickly as possible:
Many other breeders also produce great auto-flowering strains (Dutch Passion, FastBuds, Barney’s Farm, etc.), but the following breeders stand out for consistency.
Zkittlez Auto is ready to harvest 8-10 weeks from germination. Every time I grow this strain the smell and bud effects are excellent
Fr om day 1 of your marijuana plant’s life to a smokable harvest, you’re looking at 2-6 months. Many factors affect the total time (especially the strain and size of the plant) but the average grow takes 3-4 months .
Ultimately, How Long to Harvest Marijuana Depends on the Desired Yields, Strain and Grow Style
Before You Start Growing Weed
Vegetative Stage: 4-8 week average (but if you want big plants it may take longer)
The length of this stage is a matter of personal preference. Most cannabis plants won’t start flowering until they’re at least 3 or 4 weeks from germination, but after that you get to choose how long your plant spends in this stage (except auto-flowering strains, which automatically start flowering in 3-4 weeks from seed). Except for auto-flowering strains, you have total control over the vegetative stage because you’re the one to ‘flip the switch’ and get your plant to enter the next life stage: flowering.
