Curious how healthy cannabis seeds look? Continue reading!
Although it isn’t always visible with the blind eye, on a quality cannabis seed you can see a pattern of “tiger stripes” or dark spots.
Color of the cannabis seed
The quality of a seed can be partially assessed by looking at the appearance. However, you have to know what a healthy cannabis seed looks like and that can be difficult. Even for the experienced grower. In this blog we therefore answer various questions such as: what do weed seeds look like and how can you see if a cannabis seed is healthy and viable?
To test the viability of a seed you can place the seed in a glass with distilled water. Seeds that sink within 2 hours have sufficient mass. These seeds generally have a better chance of sprouting than seeds that still float.
Note: the moisture from your fingers can damage the seed. Please use linen gloves to prevent this.
Immature seeds tend to be light in color and have a soft outer shell.
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
Are you ready to grow?
Make sure the area the seeds are in is warm, somewhere between 70-85°F.
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

We know that determining the sex of cannabis seeds cannot be done. However, it’s unclear as to whether environmental factors have any place in determining the sex of marijuana plants.
While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.
Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.
Common myths on identifying the sex of a cannabis seed
MSNL Team / 3rd February 2017
While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.
So where do all the myths from sexing cannabis seeds come from?
