grey weed seeds

If, on the contrary, the seeds seem too big, this may be caused by a lack of macronutrients during the plant’s growth cycle. As any grower with certain experience will know, calcium deficiencies are corrected by adding calcium and magnesium, a combination that helps reestablish the perfect nutritional balance of plants.

Another aspect that can be misleading is the fact that a ripe, freshly-harvested cannabis seed has a brighter and darker colour than after it’s been packaged for 1 to 2 months.

The size of cannabis seeds

Some customers, for instance, contact us to tell us that they have bought Critical + seeds and they believe they look too small. But this is a normal feature of this strain: we’ve seen millions of Critical + seeds and we can confirm that they are naturally smaller than others. It is therefore incorrect to think that this is a sign of poor quality.

Yet again, this is a misleading physical attribute that does not guarantee the germination potential or overall characteristics of a seed. A high-quality strain can also be light or dark grey in colour.

However, a greenish colour is a clear sign of immaturity, which means that the seed hasn’t developed fully or it hasn’t received all the necessary resources to reach full maturity. In this particular case, if you purchase seeds with this colour you need to contact your supplier immediately and try to have them replaced.

Bag seeds you randomly find in your buds aren’t supposed to be there, so that means that the genetics are a toss-up. Even if the seeds started with good parents, there’s no telling how high or low the quality will be. Unfortunately, the only way to find out is to grow it… Some growers win the genetic lottery, but many others lose out.

If you talk to breeders, you’ll learn that when you breed two “star” strains together you don’t always get what you’d expect. It seems like every one of the seedlings (or at least most of them) should be capture the best qualities of both their parents.

Did you know that the “stripes” on cannabis seeds are actually part of a protective coating? The “pale” seeds in this photo are actually just regular seeds with the coating rubbed off!

Even if you’re starting with the best, most fresh seed stock, occasionally you’ll get an individual seed or plant that just doesn’t grow as well or quickly as the others, or maybe you’ll get a super awesome seedlings that just starts kicking butts and taking names from its first moment.

Growing with bad marijuana seeds is particularly harsh on growers of all levels.

Over the years, some of my very best plants came from flimsy, light brown seeds that very likely would have been easy to crush between my fingers.

These are pot seeds you might get from a friend, or maybe you have them stashed somewhere and forgot how you got them. In either case, if the shell of the seed looks beat-up, it may not germinate as well or quickly as seeds that were stored in good conditions.
