With this said, you may get lucky if the strain they were growing really is prime. In this case, it’s worth carrying out the following test to see if it’s worth germinating.
The color and feel of a seed, on the other hand, can tell you a little more about its maturity and, potential to germinate or grow into a healthy seedling.
This is absolutely not true. As we explained earlier, cannabis seeds naturally look different, and no single physical trait of a seed can tell you whether that seed contains the genetics for a male or female plant. The only way to tell a female cannabis plant from a male is by looking at its flowers when it begins to sex. Don’t be fooled into throwing out perfectly healthy seeds just because a popular internet chart told you so.
Germinating All Your Seeds Regardless
Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.
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.
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.
Mature cannabis seeds usually have a hard outer shell that can vary in color from very dark (or almost black) to very light grey and may have tiger-like stripes. You should be able to firmly press these seeds between your fingers without damaging them.
However, that’s not how genetics works most of the time. Without intensive breeding and backcrossing, when you mix two random plants you often end up with only a fraction of the seedlings capturing the best of both parents.
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!
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.
When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!
If growing with seeds that were produced without a male plant around, the seeds sometimes end up being hermaphrodites, which means they grow both male pollen sacs and female flowers (again, something you don’t want).
Even if you’re starting with the best, most fresh seed stock, occasionally you’ll get an individual seed or plant that just doesn’t grow as well or quickly as the others, or maybe you’ll get a super awesome seedlings that just starts kicking butts and taking names from its first moment.
Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!
