5. Float Test

The best seeds have a hard outer shell with a smooth, uncracked surface, while undesirable seeds have soft surfaces that crinkle, crack, or crumble completely quite easily.

3. Hardness & Durability

Like with any crop, a successful cannabis harvest starts with high-quality seeds but knowing how to identify the best ones can be tricky even for growers with years of experience. To help give you an idea of what to look for when preparing for your marijuana garden, here we talk about how to identify quality cannabis seeds on sight.

High-quality seeds have certain aesthetic qualities that set them apart from seeds that aren’t as healthy. The most viable seeds are brown, tan, or even black, as immature seeds are lighter colors like white, yellow, and pale green. Some people even claim that the best seeds feature dark spots or stripe patterns and that there should be a healthy sheen on the surface when held under light, like a fresh coat of wax.

You can identify quality cannabis seeds by their size and shape, especially when you can compare several seeds side-by-side. The largest seeds with the most symmetrical round or teardrop-shape are the best quality, while immature seeds are small and often have an irregular shape.

Control the Height of Your Marijuana Seedlings

It’s hard to point to the exact moment in time when a young plant stops being a seedling and begins its vegetative stage. You’ll see it happen when your cannabis starts to get noticeably bigger overnight. It may just grow higher, or rapidly develop side branches, or its leaves will get very large very fast. When you witness this sudden spurt in growth, congratulations: the vulnerable seedling stage is over and the plant has started vegging.

When the seedling sprouted, the pair of cotyledons will be ‘glued’ together – the way they used to be inside the seed, but soon they will move apart, and you will see the first tiny pair of true leaves tucked between them. Of course they will be whitish or yellow, too, at first.
