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.
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.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
Keep in mind that the simple process of packaging and storing cannabis seeds can also affect their appearance. Abrupt changes in humidity, temperature, or light exposure can make some seeds appear darker or lighter than others, but ultimately have no effect on their quality.
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.
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.

Aside from darkness, there are several factors also which you need to consider to successfully germinate your marijuana seeds. These are water, oxygen, and temperature.
10 Markers of a Quality Marijuana Seed
Weight often goes hand-in-hand with size, but heavier seeds are generally of higher quality than lighter ones. The older a seed gets, the more potential loss of moisture and nutrients, reducing its overall weight. Damaged seed, which has been cracked can potentially lose those same necessary qualities.

You may hear the phrase “on and off” in seed germination. Phytochrome Red or Pr is a pigment that will absorb red lights, this pigment is usually found in leaves. However, seeds have also Pr which enable them to react when they will receive light. Under the light, your marijuana seeds will absorb other light’s spectrum which will cause the hormones to release alterations of its biological functions. As a result, your marijuana seeds will turn on and off thus delaying its germination and sometimes will make the seeds dormant.
This is why seeds have to be germinated in the dark.
