The key is to not rub too hard. A good way to accomplish this is to use fine sandpaper and roll it up, so that the abrasive side is on the inside. Put the seeds inside this little tube and cover the two ends with your hands.
Environmental factors don’t affect the outer shell alone. They have an affect on the insides as well and can cause the seed to go bad, while, in many cases, still looking perfectly good. Let’s take a look at the main factors that will cause your weed seeds to go bad.
If conditions are too humid, the seed can rot. And similar to warm temperatures, higher humidity levels signal germination, leading the the same issues.
Sandpaper Outer Layer
Placing a desiccant inside the mason jar with the seeds ensures a steady, low relative humidity level. Replace the silica gel packs or other desiccant every 6 months or so. In a pinch, you can also use grains of rice, but you’ll want to replace those more often.
But environmental factors can also break down the protection. If the shell dries out due to a lack of moisture, it becomes harder and more brittle. It is more likely to crack, but even if it doesn’t, a harder shell no longer lets in moisture and the insides dry out and die.
The best thing you can do to keep cannabis seeds from going bad is to provide the correct environmental conditions. In other words, to avoid any of the factors listed above. It is also important to start with quality seeds, so make sure you buy seeds from a reputable seed bank.
Now shake this for a few minutes. The seeds will knock against the sandpaper and it will do the task for which it is meant, without scraping off too much of the shell.
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.
Quality seeds are the key to healthy plants and good harvests. While proper feeding/watering and good light quality obviously also affect the health and yield potential of your plants, starting a grow with top-shelf genetics is equally, if not more important. But how exactly do you tell quality cannabis seeds apart from the rest? In this article, we’ll show you exactly how to spot top-quality cannabis seeds, avoid duds, and start your grow off right.
Can You Tell The Sex Of Cannabis Seeds From Their Appearance?
A solid way to obtain great seeds is to find a reputable seed bank. These companies pride themselves of their breeding skills and make sure that their customers receive exactly what has been advertised. They have reputations to cater to, so delivering anything less would only harm their image.
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.
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.
