how to grow autoflowering weed

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.

Is the seed viable?

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Transplanting germinated cannabis seeds

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.

Please don’t stuff seeds in plastic containers that make life hell for the poor roots. Use porous containers such as fabric pots or even Airpots to help the plants grow as much as possible. Autoflowers are typically small, but they need containers that are at least 5-8 liters in size.

For example, cannabis needs more nitrogen in the vegetative stage. In the pre-flowering stage, nutrients with more phosphorous are preferred, and in the flowering stage needs a lot more potassium than nitrogen or phosphorous.

4. Choose the right medium

Yes, you can, although it’s not recommended because it can affect the yields. To prevent shocking your autoflowers and consequently affecting yields, it’s recommended to transplant 7-12 days after germination and if possible, use rooting cubes to prevent damaging the roots.

6. Do not transplant

Often referred to as popcorn buds, the lower portions stay small. However, harvesting the main colas and leaving the popcorn buds on the plant for a week more will increase yields dramatically. Be patient, and let Mother Nature do the rest for you! If you avoid these common mistakes when growing autoflowering cannabis, you’ll soon be rewarded with potent resinous buds that will last a long time if stored properly.
