What Makes a Cannabis Seed High Quality? marijuana seeds in wooden bowl There are several factors that go into determining whether cannabis seeds are high quality or not. First of all, they must be allowed to fully mature before harvest. Next, they must be properly stored as to not acquire mold or other pathogens that can spoil them. Seeds should be stored in a dark, cool place and used within 16 months, or frozen for future use. The most important factor in seed quality is genetics. To grow quality cannabis, you need good genetics. Some less scrupulous breeders will simply cross a nice female with a random male and sell the resulting seeds. Other breeders will take their time crossing and backcrossing plants to stabilize the most desirable traits, while still producing an array of different phenotypes. This group represents most of the seeds on the market. Really dedicated breeders have worked for years to create “inbred lines”, or IBLs, that will produce plants with very little noticeable difference. IBLs represent only a small fraction of the cannabis seed market, as they are generally used by breeders and not by cannabis producers. Factors That Impact Your Cannabis Strain: Part 1, Genetics How Do Cannabis Seeds Germinate? Germinated marijuana seeds In the wild, female cannabis plants drop their seeds as they die in the fall, then when the warmer, wetter weather of spring comes around, these seeds sprout and become new plants. Traditional outdoor methods used for centuries involve simply broadcasting seeds by hand onto cultivated fields. There are many methods used by modern growers to germinate seeds. The easiest is to put the seed in a light potting soil mix covered by ⅛ to ¼ of an inch of soil. Keep the soil moist and relatively warm (50-70 degrees Fahrenheit) until the seed
