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.
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.
One of the keys to achieving healthy and vigorous cannabis plants is starting with high-quality seeds. Of course, prime nutrients, adequate watering, and good light quality all contribute to the final yield obtained. But starting a grow with tip-top genetics is equally, if not more important. Carefully sourcing high-quality cannabis seeds will ensure you are receiving the exact genetics you are looking for. Not only will they provide you with the desired cannabinoid and terpene profiles, they will help you to avoid dud seeds.
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.
Darker and better-quality seeds will feel firm to the touch. Place the seed between your thumb and index finger and give it a squeeze, not enough power to bend metal, but enough to tests its resilience. If the seed feels firm and does not bend or break under the applied pressure, then it’s more than likely worth planting.
Are your seeds light or dark in colour? Are they tough under pressure or do they turn to dust? These are some of the ways to tell if your seed is healthy and worth growing.
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.
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.
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.
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.
Growing with bad marijuana seeds is particularly harsh on growers of all levels.
This is mostly because it’s tough to pinpoint when the seed itself is the actual problem. Most growers will blame themselves for a problem that shows up in their grow long before they assume it’s the seeds.
So I’m a big believer in the fact that if you put the seed in the ground and a fast-growing healthy seedling comes out of it, it was a viable seed! Don’t toss a seed you are really interested in just because it’s a little pale; give it a chance (I’m talking more about tan seeds, it’s very unlikely a yellow seed will sprout)!
One of the best ways to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder.
Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!
Seeds are a little nugget of genetic material than can hopefully grow into a plant. And like all other genetic material, it doesn’t last forever! Although seeds can be viable for quite years and years after they’re first produced, the chances of them successfully germinating goes down over time (and old seeds also tend to take a lot longer to germinate than fresh ones). The resulting seedlings are also more likely to be slow growing. But sometimes they sprout like they were born yesterday!
The term ‘bad seeds’ usually refers to any type of seed that has a significantly higher likelihood of causing problems in a grow. I’ll cover the most common reasons for bad seeds in this tutorial!
When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!
Over the years, some of my very best plants came from flimsy, light brown seeds that very likely would have been easy to crush between my fingers.
