how fast can you grow weed

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.

Take meticulous notes on when and how you perform each step, as well as what the weather is like. Other notes can include how much water you give plants, at what intervals, and how much nutrients you give them. Pictures will also give you a better sense of how your plants look along the way.

The first marijuana plant stage begins with the seed. A cannabis seed should feel hard and dry, and be light- to dark-brown in color. An undeveloped seed is generally squishy and green or white in color and likely won’t germinate.

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.

Seedling stage

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.

Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight

Flowering stage length: 8-11 weeks

Important dates for growing marijuana outdoors

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.

Be mindful to increase your watering as the plant develops. When it’s young, your plant will need water close to the stalk, but as it grows the roots will also grow outward, so start watering further away from the stalk in the soil so roots can stretch out and absorb water more efficiently.

Total growing time needed: 3-5 months on average

This article will give you the total time breakdown, so you can plan out the details of your grow in order to achieve the harvest times you desire:

Before You Start Growing Weed

Get seeds or clones: 0-4 weeks:
If you’ve found seeds in your bud or have instant access to genetics (like knowing a grower or buying seeds/clones locally), you’re already good to go. If you order from a seed bank overseas (especially US residents), expect to wait 1-4+ weeks to get seeds. Shipping time depends on the shipper and how fast the mail gets delivered. Sometimes seeds get caught up in customs for weeks. Make sure to always order from a trustworthy vendor.

Time Needed to Grow Weed, From Seedling to Harvest

Total preparation time needed: Up to a few weeks

How fast can you grow weed

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.

There are a couple of hacks that could speed up cannabis growth, including growing autoflowering hybrids, growing from clones instead of seeds, growing hydroponic weed, and changing up the stressors put on the plant (although this option is probably best left to more experienced growers).

For those looking to grow cannabis more quickly or achieve higher yielding strains, indica is the way to go. With a shorter flowering period – about eight-to-twelve weeks – plus a generally higher end yield, growers often prefer them because they can be cultivated in more frequent cycles indoors, while outdoor growers can time several growing cycles before the weather turns cold.

Since hybrid seeds 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.

This cerebral and uplifting cannabis variety poses more challenges than growing indica. In addition to their longer ten-to-twelve week flowering period, plants grown from sativa seeds tend to produce a smaller yield (although this is certainly not true of all sativa strains).

A very loose breakdown of a growing timeline could look like this:

One seed company says they have a strain that can go from seed to harvest in 49 days. Before you buy seeds from any company, be sure to do your own research on quality and reputability, and make sure you’re getting a strain that suits your consumption habits and preferences.
