Genetics and Origins
Grapefruit Haze Autoflower is the product of years of careful breeding and refinement. The father, an F4 Grapefruit male, passes on sweet, hardy traits that carry through to its offspring. Crossed with a meticulously chosen Super Silver Haze female, it gives a strain that embodies the best characteristics of both parents.
The Super Silver Haze used for this cross was selected for its dense buds, strong Haze flavor and uplifting effect. Its silvery, crystalline appearance complements the sweetness and robustness of the Grapefruit male, for a harmonious hybrid. Over the years, Next Generation Seeds has fine-tuned this strain to enhance its flavor and potency, resulting in a superior cannabis strain.
