Few purple strains carry the reputation of GrandDaddy Purple, a Californian classic that has shaped the whole purple category. This feminised cultivar is built from Purple Urkle and Big Bud parentage and sits at roughly 70 per cent indica with a touch of sativa. Expect vivid, deep purple and violet buds that are dense and firm, dusted with a glittering layer of resin. The flavour leans towards juicy grape and sweet berry, finishing with an earthy, faintly pungent note. Its effects are described as soothing and relaxing, with a heavy body feel and a euphoric lift to the mood. Plants stay compact, which suits indoor spaces with limited headroom, and they are considered moderately easy to grow. Indoors they reach about 100 cm, while outdoors they can grow considerably taller. Flowering takes roughly eight to nine weeks, and outdoor harvests typically arrive in October. Training methods such as topping and LST are suggested to improve light penetration. THC is stated at 25 per cent, making this a potent choice for experienced growers and enthusiasts.
