Of the many different types of seeds available, it is important to understand exactly what feminized means.
Feminized seeds contain two female (x) chromosomes with no male (Y) chromosomes guaranteeing female plants which produce THC-rich flowers.
Let’s look into this in more detail: Only female cannabis plants produce high levels of THC, other cannabinoids, and terpenes. Marijuana is a Dioecious plant, which means – there are separate male plants and female plants, not both. Some other species of plant have both male and female reproductive parts in the same plant, this is NOT how marijuana plants work. That means that even though male weed plants will still produce very small levels of THC, they won’t be as potent or tasty as female plants.
In addition, male plants produce pollen that, if it lands on a female, makes it produce seeds, which we all know is a red flag for lower-quality weed. Why? because once it's pollinated all the plant's energy goes into making seeds, not big fat sticky buds. When you’re buying seeds, you’ll often see ‘feminized’ seeds or regular seeds. If the seeds are regular, they can end up growing into females or males. This increases your risk of male plants pollinating your females and ruining the entire crop overall.
