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.
Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.

Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
How to sex a pot plant
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
Platinum Cookies is essentially a more potent version of the popular Girl Scout Cookies strain.
Seeds in your buds aren’t good or bad. They are simply the result of pollination while the buds were growing. A few seeds here and there won’t make much difference in potency, though potency may be lower if the buds are very seedy.
However, I have been surprised to find some very flimsy or pale seeds sprout and produce amazing plants (we aren’t breeding cannabis for hard seeds after all). When in doubt, I highly recommend doing the true test to see if the seed is viable – try to germinate the seed and see if it sprouts !
The best way to tell if a seed is viable is simply to try germinating it
Are “found” seeds good to grow?
The main problem with seedy weed is that you are getting less smokeable bud for the amount of total mass there. If buds are seedless, you get more bang for your buck. Seedless buds are known as “sinsemilla” (“sin semilla” is Spanish for “without seeds”) and are considered to be the highest quality and most potent type of weed.
Sometimes you don’t see the seeds until they fall out of your buds
Seedy weed is fine to smoke, though you should remove the seeds if possible (they have no THC and will pop if you smoke them). Unless there are tons of seeds, bud potency is unlikely to be affected.
What causes seeds in buds?
The biggest problem is that seeds often don’t “breed true” to the buds that they came from. The resulting buds may end up nothing like the buds you found them in.
Pollen typically comes from the pollen sacs of a male cannabis plant. Male plants spray pollen everywhere when their flowers are mature. Sometimes female cannabis plants will produce pollen (known as herming) due to genetics or stress. Any source of pollen, whether the plant is male or female, can pollinate buds in the vicinity and cause seedy buds.
A final note: Make sure you check the laws of your local area – certain municipal governments have different laws about growing marijuana when compared to just imbibing it. Make sure you’re not breaking any laws with your hand-grown marijuana – you wouldn’t want it taken away from you after all your hard work!
The germination process can take up to around 10 days, but most will begin the process after 2-3 days. Any that don’t show signs of opening up and spreading roots can be safely thrown away.
Even using the towel and plate method, it’s possible that around a quarter of your seeds still won’t germinate.
The reason we don’t just put the seed into the soil is that marijuana seeds can be a bit particular – they require conditions to be just right, otherwise, they’ll fail to germinate and simply sit there. By putting them in a little protective case made of paper towels and plates, the seeds get the perfect environment to germinate.
So Can You Plant the Seeds from Your Marijuana Buds?
Water activates the growing enzymes within the seeds, encouraging it to strip off its protective outer layer and start creating roots to lay into the ground.
However, sometimes a marijuana plant is harvested just a bit too late. Perhaps it got the chance to develop a bit longer than it would normally, or maybe the grower was just trying something new.
To germinate a marijuana seed, it takes a little more love and care than with some other plant seeds.
Firstly, take a plate or some other surface with a divot in it and lay a wet paper towel across the plate’s surface.
Planting the Seeds
However, the leaf isn’t actually very interesting. It just absorbs sunlight and feeds the plant. According to the United Nations report* on cannabinoid levels between both male and female plants, the large leaves of some specimens only contain about 0.3% THC and 0.7% CBD, meaning you’d be hard-pressed to get any kind of high from the leaves.
Now that we know what they are, how do we choose and use them?
