Mephisto Genetics Double Grape is an F7 feminised automatic that brings two grape titans together: Sour Stomper and Grape Crinkle. From the first rub, the nose spills ripe red grape and sour-candy notes over a subtle ribbon of gas, echoed in the flavor as sweet grape pop with a tart edge. Plants stay compact and bushy, 55-80 cm tall with an open structure that welcomes light, stacking tight, resin-caked colas. In ideal conditions she finishes fast in 70-80 days from sprout and rewards with around 90-140 g per plant, or solid square-meter yields indoors, making her a favorite for novices and extractors alike. Lab reports on select phenos have reached 31.8% THC within 36.9% total cannabinoids, while CBD remains low; expect a hybrid ride that opens with an upbeat, euphoric sparkle before settling into a happy, body-softening calm. The terpene ensemble commonly leans toward myrcene, limonene, and beta-caryophyllene, reinforcing its grape-candy core with citrus lift and peppery warmth.
