How Long Does It Take to Grow Weed?


I get asked this all the time, so today I decided to answer, once and for all, how long it really takes to grow.

How long does it really take to grow weed?

The short answer is, from Day 1 of your weed plant's life to actually smoking your harvest, it takes...

8 weeks - 7+ Months

That's why most growers won't give you a straight answer. The honest truth is, many factors will affect the total time.

So a more fair answer might be to say that the average grower takes 3-4 months to grow, harvest and quick-cure a few ounces to a pound of buds per plant (depending heavily on your strain choice and setup).

And, for at least the first time you grow, you also need to consider the time needed to get your equipment and seeds/clones.

I'm going to give you the total breakdown, so you can plan out exactly what your grow needs to look like in order to achieve the harvest times you desire:

  3. Post-Harvest (before you smoke you have to do this stuff too)

Before You Start Growing Weed

Total time needed: 0 days - 4 weeks

Here's the breakdown...

Get equipment - 0 days - 2 weeks

Get seeds or clones - 0-4 weeks: if you have instant access, this doesn't take any time. If you order from a seed bank, this step takes about 2-4 weeks to get seeds.

Time Needed to Grow Weed, From Seedling to Harvest

Total time needed: 6 weeks - 5+ months

Here's the breakdown...

Germinate your seeds: 1-5 days (skip this step if you start with clones)

Vegetative Stage:  2 weeks - 2+ months.

The length of this stage is a matter of personal preference. You get to choose how long your plant spends in this stage, because you're the one to 'flip the switch' and get your plant to enter the next life stage, where she starts flowering.

Wait, how do I switch my plant from the vegetative stage to the flowering stage?

When you start with a seed, even with an auto-flowering plant, you will always have at least 2-3 weeks of vegetative growth before any buds start forming. Growers generally allow their plants to stay in the vegetative stage from a few weeks to a few months.

The size your plant achieves in this stage has a lot to do with your final yields, since bigger plants produce more.

Some people put their seedlings or clones right into the flowering stage if they want to harvest quickly (and grow extremely small plants). For example, super-stealth growers who are growing in small hidden spaces, like out of a computer case (or better yet, a space bucket), would want to put their seedlings into flowering nearly right away to keep their plants as small as possible. 

I personally recommend at least 3 weeks or more in the vegetative stage with 18+ hours of light each day for the best results. Plants that are forced to start flowering sooner than that don't yield much compared to how much work you put in, and the plant usually won't start forming any flowers until about week 3 anyway.

A good rule of thumb...

Your plant will likely double in size (or more) from when you first put her into the flowering stage, so make sure you end the vegetative stage before your plant reaches half the final height you want, or she may overgrow your grow space during the flowering stage!

To give you an idea as to what your FINAL plant will look like depending on how long she spends in the vegetative stage...

Marijuana grown in hempy solo cup ← This plant didn't spend any time in the Vegetative Stage. She was given 12-12 lighting almost immediately after sprouting. She's so small that she spent her whole life in a solo cup. I weighed down the bottom of the cup with rocks so she didn't fall over.
Marijuana grown under LED lights ← This plant spent about 4 weeks in the vegetative stage, with some plant training to create a well-managed indoor plant, before being changed over to flowering. (pic thanks to Endive from GrowMedical420.com - view a complete grow journal by this grower!)
Medical marijuana plant falling over from buds ← This girl (one of my very first plants, from 2004) spent a little more than 3 months in the vegetative stage before I realized to turn her over. She got way too tall for her space and started falling over. Click for a closeup. :)

 

 

 

Flowering Stage: 6 weeks - 3 months

Here's the breakdown... 

The length of time needed to stay in the flowering stage depends heavily on the strain. Once you have switched your plant into the flowering stage  Here's a list of popular strains by length of flowering period:

Short (6-8 weeks)

Medium (8-12 weeks)

Long: (12-14+ weeks)

  • Almost any Haze strain, including one of my all-time favorites to grow, Haze 1

As you can see, most strains are in the mid-range as far as how long they take to flower.

And remember, there's a 2-3 week harvest window for most plants, and keeping your plants in the flowering stage for a bit longer tends to increase your yields. This is because the plants tend to really bulk up their flowers once they've become 'ripe'.

So oftentimes, even though you could harvest at the shortest recommended time, waiting an extra week or two will give you an extra 20-30% more yields.

Note: Please realize that a 6-week plant is going to produce just a few grams of smokable harvest. With a 4 week vegetative stage, the time from seed to harvest averages 3-3.5 months for me growing with CFLs in coco coir, and with that setup I get 6-10 ounces per plant, depending heavily on strain.

Post-Harvest (before you smoke you have to do this stuff too)

Drying - 3-10 days
Curing - 2 weeks - 2+ months

2 weeks is considered the minimum time to cure your buds, but I personally cure all my buds for a month or longer.

Curing really seems to make the effects of buds feel less 'speedy' and be better suited to medical applications like treating anxiety, reducing pain, and improving feelings of depression.

Total post harvest time needed: 2.5 weeks - 2+ months

So, after you've bought seeds and equipment, that brings me back to my original answer...

Total Time To Grow (and Be Ready to Smoke) Your Own Weed: 8.5 weeks - 7+ Months

Average: 3-4 months from seed to smoking your harvest (at least with bubbleponics or growing indoors with coco coir).
