how long does it take to grow marijuana from seed

However, growing cannabis is not exactly like taking care of a potted plant. And one thing a houseplant certainly does not need is a deft hand to guide it through its grow cycles. After all, daisies will bloom if you can at least remember to give them some water and sun. Cannabis? Not so much. To grow cannabis that can be consumed for its intended purpose, what it really needs is time and attention.

Do you have any experience growing cannabis at home? How long did it take you from seed to harvest? Share your stories in the comments below.

The Time it Takes to Grow Cannabis

If you do decide to grow your own cannabis, plan on approximately seven months from when you plant to when you can consume your homegrown stash.

Grow times for cannabis plants vary widely, but on average, are about three-to-five months for indoor grows. However, there are many factors that could add or subtract from that range, including whether you choose to grow from a clone or a seedling, the target yield (how much consumable product) and the growing method, whether indoor, outdoor, greenhouse, hydroponic, coco, etc. A very loose breakdown of a growing timeline could look like this:

A genetic mix of both indica and sativa strains, the growing time for hybrid marijuana strains may vary depending on which way the genetics lean. But, on average, hybrids tend to grow faster in the vegetative stage like a sativa, but may have a shorter flowering period like indica, about six-to-ten weeks. Since hybrids are a true blend of both sativa and indica, cultivators often prefer to grow them because of their higher output, generally faster growing time, and consumer appeal.

How to grow marijuana as quick as possible:

Once your plant is harvested, there is a drying and curing process which takes about a minimum of two weeks before your buds are “ready” for use.

Long Anwer:

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:

Additionally, many growers prefer to ‘cure’ their buds for longer than the 2-week minimum for added flavor and bag appeal, which accounts for why some grows could take several months from seed to smokable harvest.

Marijuana light cycle: 16 hours a day

Vegetative stage length: 3-16 weeks

If you’re growing weed indoors, you can grow whenever you like. Keep in mind that the outside environment will affect your grow space—you may need to add heaters in the winter or fans and ACs in the summer. Other than that, you can start seeds whenever you like and flip them into flower whenever you like, depending on how big you want the plants.

What are a weed plant’s growth stages?

Be very careful to not overwater the plant in its seedling stage—its roots are so small, it doesn’t need much water to thrive.

Generally speaking, it takes anywhere from 10-32 weeks, or about 3-8 months, to grow a weed plant from seed. It’ll be quicker if you start with a clone or an autoflower seed.

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.

If you buy a clone from a grower or breeder it will be a seedling, so you can skip the seed germination phase.
