how to know if a cannabis seed is good

The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.

Are your seeds light or dark in colour? Are they tough or do they turn to dust when you press them between your fingers? These are just some of the ways to tell if a seed is healthy and worth growing. Keep reading to learn more.

We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.

Source Your Seeds Well

However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.

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).”

It’s important to only conduct this test if you are planning to germinate the seeds immediately afterwards. The viable seeds that sunk to the bottom of the glass will have taken in water, crossing the membrane of the seed and signalling that it’s time to come to life—activating germination.

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.

This is mostly because it’s tough to pinpoint when the seed itself is the actual problem. Most growers will blame themselves for a problem that shows up in their grow long before they assume it’s the seeds.

So depending on how the seed was originally made, bagseed often has a lot of variety. Even if the buds you got were an incredible quality, it doesn’t necessarily mean that the seeds will produce buds like that. If you’ve ever gotten involved with breeding or growing other types of specialized plants like roses, hops or even apples, you’ll know that seeds rarely breed “true” to the parents, and cannabis isn’t any different.

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.

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!

That being said, sometimes bagseed is all you have, and lots of growers get lucky!
