Grapefruit Autoflower Origin and Genetics

The Grapefruit Autoflower strain comes from an esteemed lineage that carries the torch of a rich genetic legacy. A tantalizing mix of Cinderella 99, ruderalis, and a mysterious strain from the grapefruit family, this strain’s genetic portfolio is nothing short of illustrious. The Cinderella 99 contribution brings in the powerful cerebral uplift and tropical citrus notes, while the ruderalis introduces the autoflowering trait, making it an easy grower. The unknown grapefruit strain infuses the dominant grapefruit flavor and aroma that give this hybrid its distinctive, mouth-watering character. While its roots are believed to stretch back to Vancouver, Canada, the Grapefruit Autoflower has traveled far and wide, inspiring a legion of hybrid strains and establishing its foothold in the annals of cannabis history.

How to Grow Grapefruit Autoflower

Growing Grapefruit Autoflower is an absolute joy for both novice and experienced cultivators, thanks to its robust autoflowering genetics. It can adapt to both indoor and outdoor environments, though it does flourish in a Mediterranean-like climate with plenty of sunlight and consistent temperatures. Its nutritional needs are moderate, and it particularly appreciates a well-balanced nutrient mix with an emphasis on nitrogen during the vegetative phase, then switching to phosphorus and potassium during flowering. From seed to harvest, the plant typically requires 10–14 weeks, a fast turnaround compared to many other strains. In optimal conditions, growers can expect an abundant yield, with indoor cultivations yielding up to 600 grams per square meter, and outdoor gardens producing around 5–15 ounces per plant. With such rewarding harvests, the Grapefruit Autoflower is a worthwhile addition to any grower’s garden.
