However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.
The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.
If you are still unsure about the quality of your seeds after analysing their appearance and toughness, it’s time to put your lab coat and goggles on. Well, not quite. This test is extremely easy and only has two possible outcomes. Fill up a drinking glass or glass jar with water (preferably spring or distilled) and place your seeds on the surface.
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.
One good way to gauge the quality and traits of a cannabis seed is to get used to how they look. Some details are glaringly obvious, whilst others take some time to identify quickly. Healthier and genetically superior seeds will exhibit darker colours on the outer shell. Shades of grey and black are signs of a good seed, sometimes displaying a tiger stripe aesthetic.
Poor-quality or old seeds will crack and crumble under pressure. If they break into parts under slight pressure, they will be unusable. But they wouldn’t have been worth the time anyway. Seeds are simply pods of a plant genetics. With time, they will age and become unusable. Seeds that are obviously past their prime are not worth wasting time on.
Healthy seeds will also look as though they have a coating of wax of their shell. This can be made obvious when exposing them to a bright light and witnessing a sheen effect.
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.
Knowing how to determine the quality of cannabis seeds will save you precious time, money, and effort. Here's how to tell the good from the bad.
