About Royal Haze
Royal Queen Seeds built Royal Haze from Amnesia Haze and Kush, landing on a sativa that runs 90% sativa to 10% indica in its makeup. THC is measured at a moderate 15%, low enough for longer sessions without the intensity some haze crosses bring. It asks for patience in the garden — ten to twelve weeks of flowering is on the long side — and it grows tall, stretching to 80-140cm indoors and 175-220cm outside, so overhead space matters. The payoff is size: 450-500 grams per square meter under lights, or around 550 grams per plant outdoors. Difficulty is rated moderate, which tracks with a haze-type plant that wants room, time, and steady feeding to reach its full stretch and yield.
