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.
Remember, just like animals and other living things, cannabis seeds are biologically different from one another (even if they are technically the same strain) and therefore will exhibit different physical characteristics. Don’t let these natural differences fool you into thinking that a larger, rounder, and darker seed (for example) is of better quality than a lighter, smaller, and more oval-shaped one.
Are your seeds light or dark in colour? Are they tough or do they turn to dust when you press them between your fingers? These are just some of the ways to tell if a seed is healthy and worth growing. Keep reading to learn more.
Conducting The Float Test
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.
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.
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.
The fact that cannabis seeds can vary in appearance has led some growers to think that the size, shape, or color of a seed dictates its quality.
It probably didn’t take long after you started smoking weed to realise the differences between cannabis buds. Despite how everyone claims their weed is top-notch, you’ve probably noticed when the flower just isn’t up to par. In contrast, when you’re holding quality cannabis, you know it right then and there.
Quick Growing Tip: Flushing plants at the right moment will prevent excess nutrients from accumulating in flowers and eliminate nutrient burn.
Types of Cannabis Buds
Quick Growing Tip: Harvest at the right moment, ensuring pistils are the right colour at the right time. You’ll need to be patient when cultivating strains like Amnesia Haze, as they have a slightly longer flowering time.
Such vibrancy signals good genetics, solid growing techniques, and adequate curing and storage. In contrast, poor-quality cannabis appears matte, dull, and pallid. These buds are often dark green to brown, pale, and ultimately unappealing.
These mushroom-shaped structures feature a bulbous head atop a narrow stalk. In this head, specialised cells tasked with resin production work tirelessly during the flowering phase. The resin exudes downward and gradually covers the majority of the surface of the flower. This resin—and its active phytochemicals—help guard buds against insect attacks and temperature extremes.
