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.
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.
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.
Source Your Seeds Well
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.
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.
We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.
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.
Although it is true that ripe cannabis seeds tend to have a dark shell that can go from brown to black, with lines that look like tiger stripes, this cannot be regarded as a quality indicator by itself.
However, a greenish colour is a clear sign of immaturity, which means that the seed hasn’t developed fully or it hasn’t received all the necessary resources to reach full maturity. In this particular case, if you purchase seeds with this colour you need to contact your supplier immediately and try to have them replaced.
If this happens to you with one of our seeds, don’t hesitate to contact us directly. Send us a couple of pictures so we can check them out, and our customer service team will replace them as soon as possible.
Cannabis seeds can also show slight changes at morphological level. It’s perfectly normal to find minor differences in the oval shape of seeds from the same batch.
This could be compared to a newborn whose physical appearance quickly evolves during their first few days of life in order to adapt to the completely new outside environment.
So we can openly say that this difference is simply visual. If we take the example of a Moby Dick seed, its dimensions will most likely be bigger than those of Critical +, although you can also find slight variations between seeds from the same strain. Don’t forget that, as with all living beings, cannabis seeds are also biologically different amongst themselves.
As most of the cannabis varieties that are currently on the market are polyhybrids, the size of the seeds can vary depending on their genetic line.
