Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.
A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.
How weed seeds work
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
What does it mean to find seeds in your marijuana buds? Is it something to be worried about?
Seeds are the result of pollination. That means the seedy cannabis buds (which come from a female plant) may have come into contact with pollen from a male plant. Therefore, it’s possible the grower didn’t identify and remove all the male plants before the released pollen. It’s also possible that the plant self-pollinated (sometimes called herming) which is often the result of plant stress during the budding phase but can also be caused by genetics.
What causes seeds?
There’s a seed in my bud!
I’ve seen some growers get impressive results with bagseed, but overall results seem to be hit or miss. Plants can grow in odd ways and often either the yields or quality isn’t as expected. The problem is that seeds often don’t “breed true” to the buds that they came from. That is why many growers either stick to clones (which are exactly the same as the “mother” plant) or purchase seeds of a stabilized strain from a trustworthy breeder, where each of the plants will grow the way you expect, and buds more consistently have the smell, yield and potency they’re supposed to.
If it’s very seedy the buds may not feel as potent, though a few seeds here and there won’t make much difference in potency. The main problem with seedy weed is that you are getting less smokeable bud for the amount of total mass there. If it is seedless, you will get a lot more bang for your buck. Seedless bud (sinsemilla) is considered to be the highest quality and most potent type of weed.
