While major crops have had the benefit of modern breeding practices, even the basics like Mendel's Law haven't been properly applied to cannabis. The terms F1/2/3 etc. are used, but most cannabis seeds are polyhybrids—their genes are full of variations. A true F1 Hybrid is the crossing of two highly inbred populations without those variations, and will display hybrid vigor and uniformity. For this seed, Humboldt Seed Company used their best, highly inbred O.G. Kush and Royal Highness, which complement each other and stay true to the popular O.G. Kush genre and high THC.
