how to tell if marijuana seeds are viable

The beginning of an epic cannabis journey

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.

Healthy and viable cannabis seeds feature a brown color that varies from a light shade to a much darker one. Some seeds are more uniform in color, whereas others feature multiple shades and tiger stripe or turtle shell patterns.

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

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.

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.

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?

Mature cannabis seeds usually have a hard outer shell that can vary in color from very dark (or almost black) to very light grey and may have tiger-like stripes. You should be able to firmly press these seeds between your fingers without damaging them.

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.

Can You Tell The Sex Of Cannabis Seeds From Their Appearance?

This is absolutely not true. As we explained earlier, cannabis seeds naturally look different, and no single physical trait of a seed can tell you whether that seed contains the genetics for a male or female plant. The only way to tell a female cannabis plant from a male is by looking at its flowers when it begins to sex. Don’t be fooled into throwing out perfectly healthy seeds just because a popular internet chart told you so.

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.

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.

Another type of bad seeds is male cannabis plants. There’s a 50/50 chance with regular seeds as to whether any given seed is male or female. The problem is that male plants will pollinate the females once they reach maturity, destroying the valuable THC content of female plants.

Cannabis seeds are surprisingly beautiful. They have a mottled brown appearance with patches of light and dark, and sometimes gorgeous tiger stripes. The seeds are also quite shiny if you view them close enough.

How to Test Cannabis Seeds

Sometimes, you can end up with ‘bad’ cannabis seeds that will cause problems later down the line. In some cases, these seeds just won’t germinate. Although this won’t ruin your entire crop, it is a waste of time and money, which can be frustrating.

Sometimes, you can tell if a seed is good or bad just by looking at it. Here’s how to spot a healthy seed:

You may not realize it, but the quality of your cannabis crop is, in part, determined before you have even begun. Seed quality is an enormous part of growing, so it’s vital to source marijuana seeds from a reputable company.
