Unlike other agricultural crops (like vegetables, fruit, or grain), cannabis hasn’t undergone the vigorous breeding techniques that ensure a stable crop. This means that you’ll sometimes sow a pack of seeds technically labeled as the same “strain,” but may end up with very different looking plants. It also means that the individual seeds you buy from a seed bank can vary in appearance.
This simple and cost-effective method is a great way to tell the good genetics from the bad; they will sink or swim, literally. Seeds that remain buoyant on the surface are more than likely of poor quality and are to be discarded. Seeds that sink to the bottom like a botanical cannonball are probably healthy and should be germinated.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”
Remember, just like animals and other living things, cannabis seeds are biologically different from one another (even if they are technically the same strain) and therefore will exhibit different physical characteristics. Don’t let these natural differences fool you into thinking that a larger, rounder, and darker seed (for example) is of better quality than a lighter, smaller, and more oval-shaped one.
It’s important to only conduct this test if you are planning to germinate the seeds immediately afterwards. The viable seeds that sunk to the bottom of the glass will have taken in water, crossing the membrane of the seed and signalling that it’s time to come to life—activating germination.
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.
There’s a seed in my bud!
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.
Are seeds good to grow?
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 does it mean to find seeds in your marijuana buds? Is it something to be worried about?
It should be dark and relatively hard. Very pale or white seeds, that can be easily crushed between the fingers, usually won’t sprout. However, I have been surprised to find some very flimsy seeds sprout and produce amazing plants (we aren’t breeding them for hard seeds after all) so 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!
Cannabis seeds are surprisingly beautiful. They have a mottled brown appearance with patches of light and dark, and sometimes gorgeous tiger stripes. The seeds are also quite shiny if you view them close enough.
Cultivating marijuana is a bit of a learning curve, so don’t worry if you mess up your crop from time to time. It will only get easier with time.
Method #1: The Sight Test
Having male cannabis plants in your garden is basically a recipe for disaster, so you want to avoid it at all costs. By the way, here’s how to figure out if your plants are male or female.
Sometimes, you can end up with ‘bad’ cannabis seeds that will cause problems later down the line. In some cases, these seeds just won’t germinate. Although this won’t ruin your entire crop, it is a waste of time and money, which can be frustrating.
The sign of a bad seller is that their seeds are consistently old, dead, and covered in powdery mildew. That said, don’t be too harsh on a seed bank if a couple of their seeds don’t work from time to time when they’re generally reliable.
