good and bad weed seeds

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.

Note: Although the hardiness of the seed was likely important in the wild, cannabis growers have been breeding plants for generations to make good buds, not seeds! We growers strive to provide an ideal germination environment that lets almost any seed germinate successfully. As a result, we haven’t been breeding for seed hardness. Just like a teacup poodle hasn’t been bred to be strong, cannabis seeds haven’t been bred to be strong. They have other qualities we love ?

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

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.

If growing with seeds that were produced without a male plant around, the seeds sometimes end up being hermaphrodites, which means they grow both male pollen sacs and female flowers (again, something you don’t want).

The term ‘bad seeds’ usually refers to any type of seed that has a significantly higher likelihood of causing problems in a grow. I’ll cover the most common reasons for bad seeds in this tutorial!

When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!

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.

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?

The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.

A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”

With this said, you may get lucky if the strain they were growing really is prime. In this case, it’s worth carrying out the following test to see if it’s worth germinating.

However, that’s not how genetics works most of the time. Without intensive breeding and backcrossing, when you mix two random plants you often end up with only a fraction of the seedlings capturing the best of both parents.

Poor-quality or old seeds will crack and crumble under pressure. If they break into parts under slight pressure, they will be unusable. But they wouldn’t have been worth the time anyway. Seeds are simply pods of a plant genetics. With time, they will age and become unusable. Seeds that are obviously past their prime are not worth wasting time on.

Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!

Bag Seeds

Darker and better-quality seeds will feel firm to the touch. Place the seed between your thumb and index finger and give it a squeeze, not enough power to bend metal, but enough to tests its resilience. If the seed feels firm and does not bend or break under the applied pressure, then it’s more than likely worth planting.

So I’m a big believer in the fact that if you put the seed in the ground and a fast-growing healthy seedling comes out of it, it was a viable seed! Don’t toss a seed you are really interested in just because it’s a little pale; give it a chance (I’m talking more about tan seeds, it’s very unlikely a yellow seed will sprout)!

One good way to gauge the quality and traits of a cannabis seed is to get used to how they look. Some details are glaringly obvious, whilst others take some time to identify quickly. Healthier and genetically superior seeds will exhibit darker colours on the outer shell. Shades of grey and black are signs of a good seed, sometimes displaying a tiger stripe aesthetic.

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.
