how long do marijuana plants take to grow

The vegetative stage of cannabis is where the plant’s growth truly takes off. At this point, you’ve transplanted your plant into a larger pot and the roots and foliage are developing rapidly. This is also the time to begin topping or training your plants.

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.

Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.

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.

Seedling stage

Harvest happens sometime between September and November. This depends on your local climate, as well as the weather that particular year—one year it could be the end of September, the next, end of October, and growers in the Pacific Northwest will have to pull down their crops earlier than those in Northern California.

The Spring Equinox is a good reminder that it’s time to kick off the outdoor growing process and start germinating your seeds.

Even if growing outdoors, a lot of growers will start their seeds inside under an artificial light to help them through this delicate stage of marijuana growth.

Important dates for growing marijuana outdoors

Marijuana light cycle: 12 hours a day

Buds typically grow the most toward the end of the flowering life cycle. You probably won’t notice much budding out at the beginning of the flowering stage, and it will slow down toward the end of the cycle, when buds become fully formed.

Average Time to Grow (and Be Ready to Use) Your Own Weed:
3 – 5 months

Seedling Stage
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.

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.

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.

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

This human-sized plant (one of my very first plants) spent a little more than 3 months in the vegetative stage before I realized I needed to turn it over to the flowering stage. It then spent another 12 weeks in the flowering stage before it was ready to harvest because it was a long-flowering strain. It got way too tall for its space (taller than me!) and started falling over. However, despite the huge size and more than 5 months of growth, it only ended up yielding about 6 ounces. This is because it was under weak CFL grow lights. Though there were a lot of buds, the lack of strong light made them airy, without a lot of weight. Click the picture for a close-up.

Before You Start Growing Weed

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.

Whichever method and strain you go with, good luck and have fun!

Indicas can be easily spotted because they are pretty much the opposite of Sativas as far as appearance. The flowers of Indica plants are typically shorter and stubbier than their tall, thin counterparts.

Hybrids are the result of crossing Indicas with Sativas. While some prefer to cultivate either pure Indica or pure Sativa strains, most growers are cultivating hybrids due to the interesting and fun variants that are produced.

The kind of equipment needed to grow weed indoors will depend on the size of the grow and the preferences of the grower. Note that the cost of cultivating weed will vary from person to person. Some can get great results from a simple setup that costs no more than $100, while others may need to spend up to $10000 for their grow operations.

Know The Costs

Growing and maintaining your own personal weed crop is one of the most rewarding experiences cannabis enthusiasts can have. While the process itself can be very time-consuming and requires some studying, it is not impossible! Plenty of people around the world have undertaken this process and gotten great results from their crops.

Let’s start with the grow times for the different types of cannabis:

Growing your own weed or starting your own operation can be exciting, but this doesn’t mean you shouldn’t approach the process prepared!

Hybrid Grow Time

They also have short flowering stages, which makes them a popular choice for experienced cannabis breeders or anyone who wants a quicker cycle. Indoor growers enjoy raising them because their shorter flowering periods mean they can produce more per year, while outdoor growers can cultivate them without worrying about climate issues or early winters. On average, Indica strains have a flowering state that lasts 8 to 12 weeks.

Be prepared to spend a significant amount of money when planning to grow weed. Buying quality marijuana seeds is not a cheap investment, and you’ll also need to invest in decently expensive equipment as well.
