Having male cannabis plants in your garden is basically a recipe for disaster, so you want to avoid it at all costs. By the way, here’s how to figure out if your plants are male or female.
Sometimes, you can tell if a seed is good or bad just by looking at it. Here’s how to spot a healthy seed:
How to Test Cannabis Seeds
If the seed cracks under slight pressure, then it’s unusable. It’s likely to be past its sell-by date.
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.
Telling good and bad cannabis seeds apart is not an exact science. Sadly, you don’t know what’s inside the seed beyond its appearance, so you won’t know what the plant is truly like until you start growing it.
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.
Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
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.
We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.
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.
Healthy cannabis seeds come in all shapes and sizes. Some cultivars produce small and compact seeds with very little room between the outer shell and the immature cotyledon leaves nestled within. Despite their small size, these seeds are completely viable when they feature other indicators of good health, such as color and age.

Despite differences in size, healthy cannabis seeds share a similar shape. They display a tear-drop body—round at one end and tapered at the other. Seeds that stray from this consistent shape may possess a genetic flaw. Seeds that are exceptionally flat or misshapen may undergo issues with germination and produce subpar plants.

After learning the indicators of size and shape, you might still be thinking: What do good weed seeds look like? Well, the quality of their shell also helps to signal how good future plants may perform. Healthy seeds boast a slight shimmer on their shells, as though growers have polished them with some wax. Unhealthy seeds look dull and matte in comparison. If you have the choice, opt for waxy seeds with a sheen to improve your results.
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.
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.
When asking yourself the question of how to tell if a weed seed is good, you need to consider where it came from. There remains a huge discrepancy between the quality of cannabis seeds from a reputable seed bank versus those found in the bottom of a mediocre bag of weed.
