Marijuana light cycle: 16 hours a day
Seed germination length: 3-10 days
Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.
The weather will start to turn and the sun will begin descending in the sky as your plants fatten up with sweet, sticky buds. It might be tempting, but wait until around the Fall Equinox to start harvesting.
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
If you need to determine the sex of your plants (to discard the males), they will start showing sex organs a few weeks into the veg stage. It’s imperative to separate males so they don’t pollinate the females.
As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.
Long: (12-14+ weeks)
These auto-flowering plants spent about 3 weeks in the vegetative stage before they automatically started flowering, and were ready to harvest just 5 weeks later. They were about a foot tall at harvest and yielded approximately 2 ounces each. Read the step-by-step tutorial to grow plants exactly like this.
This is one of the most common questions we receive from curious soon-to-be indoor cannabis growers: How long does it really take to grow weed? What’s the growing timeline?
Additionally, curing gets rid of any ‘cut grass’ smell, harsh taste and other undesirable traits of some freshly dried buds. Over time with proper curing, those traits will be replaced by the ‘real’ smell and potency profile of your buds.
Time Needed to Grow Weed, From Seedling to Harvest
This article will give you the total time breakdown, so you can plan out the details of your grow in order to achieve the harvest times you desire:
Two weeks is considered the minimum time to cure your buds, but I personally cure all my buds for a month or even a bit longer because the buds continue to improve for several more weeks.
Germinate your seeds: 1 – 7 days
Seedlings can sprout in as little as a day, but by 3-5 days, they should be good to go. If you have access to clones, you get to skip this wait.
Before You Start Growing Weed
Total growing time needed: 3-5 months on average
This marijuana plant spent about 6 weeks in the vegetative stage before being changed over to flowering and yielded just over 6 ounces at harvest. View the complete grow journal with instructions on how to grow your plant so it looks just like this at harvest!
It can take anywhere from 4 to 8 months to grow a cannabis plant, this varies based on where you’re growing. If you have an indoor grow room, your plant has the ability to flower after only a few weeks!

The quality of your plant depends on your knowledge of the cannabis growth stages and the lifecycle of your plants.
