tiger striped marijuana seed

Are your seeds light or dark in colour? Are they tough or do they turn to dust when you press them between your fingers? These are just some of the ways to tell if a seed is healthy and worth growing. Keep reading to learn more.

We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.

Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds

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.

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.

The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.

Did you know that the “stripes” on cannabis seeds are actually part of a protective coating? The “pale” seeds in this photo are actually just regular seeds with the coating rubbed off!

If a cannabis seed was produced with a male doing the pollinating, it means that about half of the resulting seeds will end up being male (which you don’t want, because only female flowers turn into bud). In that case, you want to determine the gender of your young plants as soon as you can so you can toss all the male ones before they start making pollen sacs.

Bag seeds you randomly find in your buds aren’t supposed to be there, so that means that the genetics are a toss-up. Even if the seeds started with good parents, there’s no telling how high or low the quality will be. Unfortunately, the only way to find out is to grow it… Some growers win the genetic lottery, but many others lose out.

Seeds are a little nugget of genetic material than can hopefully grow into a plant. And like all other genetic material, it doesn’t last forever! Although seeds can be viable for quite years and years after they’re first produced, the chances of them successfully germinating goes down over time (and old seeds also tend to take a lot longer to germinate than fresh ones). The resulting seedlings are also more likely to be slow growing. But sometimes they sprout like they were born yesterday!

One of the best ways to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder.
