If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
Transplanting germinated cannabis seeds
Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
There’s a seed in my bud!
What does it mean to find seeds in your marijuana buds? Is it something to be worried about?
Does it mean the weed is bad?
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.
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.
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.
The term sinsemilla is derived from the Spanish words “sin” (meaning “without”) and “semilla” (meaning “seed”) to mean as stated, without seed. This word has been associated with seedless cannabis flower since the 1970’s in North America but there is some evidence of it dating back further to countries like India! To clear up a few myths; sinsemilla is NOT a strain or genetics. It is a female cannabis plant that has not been exposed to male plants (aka not fertilized).
If you’re looking at your weed and you’ve noticed it has seeds in it, it’s important to figure out why. This will help to determine whether or not it is bad they are there. There are two main reasons why you may have seeds in your weed.
Saving the Seeds
Growing from home allows you to control many factors, so you can expect higher quality cannabis. If you are able to grow indoors, theres an even lower chance of your cannabis plants getting fertilized, as you would have to have the males in the tent/ grow box with them! When using a Grobo, you never have to worry about male plants being too close to your females.
This doesn’t mean it is bad for your health but we advise against smoking seeds. Please remove them as you see them – you may find them crushed up in your grinder! The presence of seeds does mean that the total mass of smokable weed is compromised with decreased cannabinoid content and quite a few unwanted seeds. Think about it this way: If you purchase an ounce of cannabis and it comes filled with seeds, you are paying for the seeds which are less desirable than the cannabis flower that you were expecting.
That said, visual cues might not be enough to evaluate your weed 100% but it can help you to conduct at best a preliminary inspection before you buy.
