Smell-first: crack a jar of cured Watermelon Z OG and the room splits between fresh watermelon rind and a sharp diesel note that lingers underneath. That contrast carries straight through to smoke, with a citrus brightness cutting in on the exhale. Blimburn built this feminized indica around 20–25% THC, so the effect lands heavy and body-focused — not a daytime workhorse. Flowering wraps in 8–10 weeks in either indoor or outdoor setups, and indoor runs consistently pull 400–500 g/m² when canopy management is solid. Difficulty is moderate, meaning she responds well to topping and low-stress training but doesn't punish small mistakes the way some high-THC indicas do. Height can stretch through early flower, so plan your vertical space before you flip.

Best suited to growers who've got a run or two under their belt and want a high-THC indica with fruit-forward flavor rather than the usual earthy-pine profile.
