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.

We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.

The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.

Conducting The Float Test

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.

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.

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.

Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.

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.

One way around this is to purchase feminized marijuana seeds. In theory, all seeds in a feminized bunch will be female – unless you buy from a disreputable grower. Unfortunately, there’s no way to tell whether a plant is male or female simply based on the seeds.

How to Test Cannabis Seeds

Unfortunately, you might still get some bad seeds sometimes. Plants are living beings and can be a bit unpredictable – even the seller might not be aware that some of their seeds are duds. With any luck, the majority of seeds you buy will be healthy and good to go.

More commonly, growers use the paper towel method. Dampen a paper towel, ensuring it isn’t soaking wet. Place this on a kitchen plate and put the seeds on top, then put another plate upside-down on top. A moist, dark, warm environment allows the seeds to sprout. Check on the seeds once a day; after germinating, you should see a white taproot emerge.

Strong seeds, however, have a better chance of germinating and growing into a healthy plant.

You can tell a lot about the quality of a cannabis seed just by looking at it. Weed seeds vary a lot in appearance, ranging from green to brown in color. They also display diversity in their shape and size, with some specimens being small and spherical, and others large and pointed.

As one of Europe’s biggest seed banks, Royal Queen Seeds understands the viability of seeds and offers some tips on how to tell if your marijuana seeds are good. There are several boxes that growers can tick to boost the odds of starting with premium seeds, from sourcing them from reputable supplies to visual assessment and easy DIY tests.

Learn how to identify quality marijuana seeds in order to start your cannabis grow in the best way possible.

Seeds found in buds obtained from your local dealer are likely of much lower quality. In general, finding seeds in flowers reflects poor growing practices. On top of this, you likely have no idea how old these buds really are. Stick to seed banks known for top-shelf genetics. Check out their reviews, and see how much data they disclose regarding each strain to confirm you’re in good hands.

We’ve all heard tales of archaeologists sprouting 1,000-year-old seeds found in Egyptian tombs. While cannabis seeds don’t possess such extreme longevity, growers often experience success cultivating seeds from two to three seasons past. However, young cannabis seeds offer the best option when it comes to viability, germination rate, and healthy plants. But, how can you tell the age of a weed seed?

Any seed that falls within this color range shows promise. Changes of color within this spectrum occur primarily due to genetic factors, but environmental variables also play a role. Some seeds take on a darker tone after being packaged for several months. Humidity, lighting, and oxidation also lead to a slight shift in appearance.
