• KC Brains: Dutch Breeding with a Long Story Behind It

Back in 1979, KC Brains got its start in the Netherlands, and things have been evolving ever since. The person behind it spent years picking up genetics from different places, always looking for something worth growing. That kind of hands-on work shaped the strains they still offer today. You will find plenty of growers sticking with their seeds because they are simple to work with and tend to hold up well, whether you are growing inside or out.
