There are several easy methods for testing cannabis seeds. Most of them can be performed before germination, saving you some time and resources. Let’s find out how to check your seeds.
For this test, you will need a cup, glass, or bowl of warm water. It should be quite warm, but not hot. It also works best with spring water or distilled water.
How to Test Cannabis Seeds
At this point, you can transplant the seed into its pot. Use a pair of tweezers and handle each seed carefully, being careful not to touch the taproot. The taproot is fragile and may break if you’re not delicate; furthermore, touching it with your hands may contaminate it.
If all else fails, it’s time to germinate. You might have no idea whether your seeds are healthy but attempting to grow them is an easy final test that will separate good seeds from duds.
Sometimes, you can tell if a seed is good or bad just by looking at it. Here’s how to spot a healthy seed:
This seedy weed could mean that the grower didn’t properly identify the male plants. Most growers will remove these plants immediately to ensure that their female plants are not pollinated.
Growing from home allows you to control many factors, so you can expect higher quality cannabis. If you are able to grow indoors, theres an even lower chance of your cannabis plants getting fertilized, as you would have to have the males in the tent/ grow box with them! When using a Grobo, you never have to worry about male plants being too close to your females.
Why This Matters
Having some seeds in the mix doesn’t mean your weed is bad. However, if your buds have a lot of seeds in them it might not be as potent as it could be. The potency can be significantly reduced as the plant’s energy is working towards reproduction and producing seeds instead of just the flower, cannabinoids (CBD, THC), trichome and terpene goodness.
The best way to avoid seedy weed is to grow your own. If that isn’t possible, purchase from a qualified vendor and not just your friend’s brother down the street. If you’re purchasing from a reputable establishment online or offline you will be able to verify the quality beforehand. You can ask questions to figure out how well the plant was treated and you can avoid otherwise low quality weed.
Before we get into the nitty gritty, let’s cover some basics. Seeds are what you get after pollination occurs. Cannabis flower (buds) are produced from the female plant. If you find seeds in your bud, that means the female cannabis plant came into contact with some pollen from the male plant, which results in your plant getting fertilized and producing seeds.
Unlike other agricultural crops (like vegetables, fruit, or grain), cannabis hasn’t undergone the vigorous breeding techniques that ensure a stable crop. This means that you’ll sometimes sow a pack of seeds technically labeled as the same “strain,” but may end up with very different looking plants. It also means that the individual seeds you buy from a seed bank can vary in appearance.
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.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
The color and feel of a seed, on the other hand, can tell you a little more about its maturity and, potential to germinate or grow into a healthy seedling.
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.
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.
