growing weed from seed to harvest

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.

When should you grow marijuana?

If you’re growing outdoors in the Northern Hemisphere, growers usually get their seeds between February and April, and you should start your seeds by the end of April. Some growers will start their seedlings inside in a more controlled environment because seedlings are more delicate, and then put their seeds in the ground outside once they’re a little bigger. If you’re growing clones or autoflowers, you have a grace period of another month or so. Plants usually need to be outside, in the ground, by the end of June.

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.

Short (6-8 weeks)

So, after you’ve bought seeds and equipment, grown a plant from seed to harvest, trimmed, dried and cured your buds, that brings us back to the original answer…

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

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:

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.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

Meanwhile the plant will grow its first “real” leaves with the characteristic marijuana shape.

In the germination process, the germ in the seed breaks through its shell and forms a root, which is known as the taproot. Germination takes anything from 24 hours to 7 days. Generally cannabis varieties with a high proportion of Indica germinate faster than pure Sativas.

Once the plant produces the full count of leaflets for each new leaf, the seedling stage is over.

2 – Seedling stage (2 to 4 weeks)

Only now can the sex be determined with any certainty. While male plants produce pollen, the female plants pour their energy into producing flowers or buds. Most growers want to prevent their female plants from getting pollinated, because then they start to produce seeds. That is why male plants should be removed from the growing area.

Cannabis is an annual plant, so its entire lifecycle takes place within a single year, with most varieties reaching the end of their life after between four and ten months. In general terms, the following four stages of life can be distinguished:

How long the seedling stage lasts depends on the variety and on the environmental conditions. The main focus of the plant is on developing a root system. This forms the foundation for its later growth.

The germinated seed can now be placed carefully into the growing medium. The plant will start to grow and force its way upwards.
