Any seed that falls within this color range shows promise. Changes of color within this spectrum occur primarily due to genetic factors, but environmental variables also play a role. Some seeds take on a darker tone after being packaged for several months. Humidity, lighting, and oxidation also lead to a slight shift in appearance.
When asking yourself the question of how to tell if a weed seed is good, you need to consider where it came from. There remains a huge discrepancy between the quality of cannabis seeds from a reputable seed bank versus those found in the bottom of a mediocre bag of weed.
Learn how to identify quality marijuana seeds in order to start your cannabis grow in the best way possible.
Healthy and viable cannabis seeds feature a brown color that varies from a light shade to a much darker one. Some seeds are more uniform in color, whereas others feature multiple shades and tiger stripe or turtle shell patterns.
Professional seed banks spend a lot of time, money, and effort breeding high-quality cannabis genetics. These specimens churn out seeds with a high germination rate, and the subsequent plants deliver outstanding cannabinoid and terpene profiles alongside excellent yields.
Once you’ve analyzed the seeds at your disposal, you can run one final check to determine their quality. The float test enables growers to set great-quality seeds aside from questionable ones. Simply fill up a glass with water and drop your seeds into the fluid. Return to the experiment 1–2 hours later. The seeds that sink are healthy and ready to germinate. Now that they’re wet, place them straight into the soil and begin the grow, as storing wet seeds can result in rot. Floating seeds are often deemed unhealthy, and some growers refuse to use them.
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.
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.
Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.
Source Your Seeds Well
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.
The fact that cannabis seeds can vary in appearance has led some growers to think that the size, shape, or color of a seed dictates its quality.
Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.
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.
