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.
Ultimately, How Long to Harvest Marijuana Depends on the Desired Yields, Strain and Grow Style
Before You Start Growing Weed
This plant didn’t spend any time in the Vegetative Stage. It was given 12-12 lighting almost immediately after sprouting. It’s so small that it spent its whole life in a solo cup, and its only light came from CFLs. I weighed down the bottom of the cup so it didn’t fall over. It ended up yielding about 0.75 oz.
Today I will show you how to plan your grow so it takes the amount of time you want!
Time Needed to Grow Weed, From Seedling to Harvest
Long: (12-14+ weeks)
How to tell if your plant is a male or female
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!
Female: Two pistils (the pistil contains the reproductive parts of a flower) will be growing on the buds (flowers grow above these leaves, one cluster on each side).
The quality of your plant depends on your knowledge of the cannabis growth stages and the lifecycle of your plants.
2. Seedling Stage
Our phone lines are open from 9am-5pm central time, Monday through Friday. Our staff is working remotely wherever possible and we will maintain a bare minimum staff on-site to perform basic operations of order processing and accounting. Our on-site staff will follow the appropriate best practices and guidelines set forth by OSHA’s latest release of "Guidance on Preparing Workplaces for COVID-19."
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.
This gives you the freedom to choose the exact strain you want without any worry about how long it will take. This gives you the freedom to grow some strains that otherwise are inaccessible to growers who are worried about timeframes.

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.
