About this release
Information on Rozay F4 Rozay F4 from Relentless Genetics is the result of four generations of selection. This regular, indica-leaning line stands out for its complex aromatic profile and exceptional resin production, making it a top pick for flavor-focused growers and for those seeking premium material for solventless extractions. Now available in Alchimia’s regular seed catalog. Rozay F4 genetics: four generations of selection Rozay F4 regular is an inbred line from Rozay F3 x Rozay F3, developed to stabilize color, aroma, and terpene expression. Its origins trace back to Sunset Sherbet crossed with Purple Bomb, the latter a Relentless Genetics creation from Black Rose (Heath Robinson) x an elite Purple Diesel clone. Purple Diesel lends distinctive aromatic nuances, while Sunset Sherbet deepens sweetness and overall complexity. After four selection cycles, many phenotypes display intense purple tones from early bloom. Indoor and outdoor cultivation Indoors, Rozay F4 finishes in about 8 to 10 weeks, with yields around 650 g/m². Plants showcase vibrant colors and a heavy resin coat, underscoring their suitability for rosin and ice-o-lator extractions. Outdoors, harvest typically falls from early to mid-October, depending on phenotype and climate. In optimal conditions, production can exceed 1000 g/plant, making it a high-yield option for spacious grows. As these are regular seeds, growers should identify and remove males during pre-flower. Aromas, flavors, and effects Rozay F4’s standout trait is its organoleptic profile. On the nose, expect cream, red berry fruits, red wine, and grape, layered with floral nuances and subtle citrus. On the palate, look for sweet caramelized grape, creamy sherbet, and gas, with a kush backdrop and Zkittlez-like fruity echoes that linger. The effect is balanced and pleasant, relaxing yet sociable and mildly euphoric. Potency is moderate to high (approximately 16–20% THC), with flavor and terpenes taking center stage. Specifications on
