Two rounded cotyledon leaves will grow out from the stem as the plant unfolds from the protective casing of the seed. These initial leaves are responsible for taking in sunlight needed for the plant to become healthy and stable.
Marijuana light cycle: 16 hours a day
What are a weed plant’s growth stages?
Buds typically grow the most toward the end of the flowering life cycle. You probably won’t notice much budding out at the beginning of the flowering stage, and it will slow down toward the end of the cycle, when buds become fully formed.
If you’re growing indoors, you can force a weed plant to flower after only a few weeks when it’s small, or after several weeks when it’s big. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until the sun starts to go down in fall for it to flower and then to harvest.
Notes on marijuana growth phases
Marijuana light cycle: 12 hours a day
After harvesting your weed, you can’t smoke it right away. Well, you can, but we would not advise it. You should dry it at the very least, but ideally you want to cure it as well.
Why would you want this period to last any longer than it has to, though?
Sativa strains generally take longer, with an average flower time of 10 to 16 weeks. Indica strains generally complete this stage in 7 to 9 weeks.
Time Required: 3 to 7 weeks
But we always advise against rushing it. After all that time spent growing, why would you want to rush it now and end up with lower quality weed?
You could also run your lights 24 hours per day. This speeds up growth, but also has negative effects on your plants. We do not recommend this either.
Because your plants keep growing. If you take them out of the vegetative stage immediately, they will be fairly small, which will limit the number and size of buds they can grow. That said, keeping them small might make sense, if you have a limited grow tent size.
Time Required: at least 3 weeks
The length of the bloom stage varies greatly. The primary factor that determines how long a plant takes to reach harvest time is the strain.
While you should never rush the process, since that will result in lower and poorer quality yields, you can speed up certain parts of cannabis cultivation to ensure you don’t waste any time and your grow comes in at the lower end of the time estimate range, not the higher end.
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 .
3-5+ months from seed to harvest
Strains from warm climates tend to have long flowering periods before their buds are ready to harvest, adding weeks or months to the time needed. Long-flowering strains often produce higher yields than short-flowering strains because buds have more time to grow. For example, Acapulco Gold takes almost 3 months after initiating 12/12 before buds are ready to harvest. However, it produces amazing yields and unique psychedelic effects.
