how long to grow weed from seed

1. Germination (1–7 days) – When your seeds “come to life” and begin sprouting.

This means you could theoretically veg your photoperiod cannabis plant as long as you want. This is also what many growers do to keep their mother plants viable for a long time. But unless you’re growing mothers, you will normally want to veg your plants until they have reached a certain height, before initiating flowering by switching your timer to 12 hours of light and 12 hours of darkness.

THE GROWING STAGES OF CANNABIS

• Germinating your seeds
Time: 1–7 days

To germinate your seeds, you can use the Royal Queen Seeds Starters Kit Feminized for optimal results. Growers also germinate using the “paper towel method”, or they put seeds in a glass of water and wait for them to sprout. Alternatively, you can just place your seeds directly in soil in a seedling pot, or even germinate them right in their final container. With good seeds, it won’t take more than 2 days until the taproot of your seeds will show, although some sativa seeds can take longer to sprout, up to 4–7 days. The time required for germinating seeds can also depend on other factors, such as temperature. It is unlikely, however, for seeds to take longer than 7 days to pop.

• Flowering stage
Time: 5–16+ weeks

Ultimately, How Long to Harvest Marijuana Depends on the Desired Yields, Strain and Grow Style

Total Time to Grow (and Be Ready to Use) Your Own Weed:
8 weeks – 5+ Months

Time Needed to Grow Weed, From Seedling to Harvest

Here’s a list of some of my favorite and best cannabis strains by the length of the flowering period:

Your plant will likely double in size (maybe a bit less, maybe more) from when you first put it into the flowering stage; this is known as the Flowering Stretch. So make sure you end the vegetative stage before your plant reaches half the final height you want, or your cannabis plants may outgrow your grow space during the flowering stage!

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.

When you start with a seed, even with an auto-flowering plant, you will always have at least 3-4 weeks of vegetative growth before any buds start forming no matter what you do. Growers generally allow their plants to stay in the vegetative stage from a few weeks to a few months.
