Barney's GrandDaddy Purple, a famed 70% indica strain with iconic California genetics.

GrandDaddy Purple by Barney’s Farm is a 70% indica / 30% sativa feminized classic bred from Purple Urkle x Big Bud, combining iconic California purple genetics with the size, density, and yield potential that made it a standout from the start. Short, bushy, and unmistakably indica in structure, it produces large, rounded, resin-coated buds in deep purple and violet tones, set against dark green foliage and bright orange hairs for the kind of dramatic bag appeal that made GrandDaddy Purple a legend. Its terpene profile is rich and instantly recognisable, led by sweet grape, juicy berries, and earthy depth, with subtle pungent and herbal undertones that give the profile extra weight. On the palate, it stays smooth, full-bodied, and candy-like, leaving behind the lingering grape sweetness that defines a true purple indica.

With THC levels of 25%, GrandDaddy Purple delivers the deeply relaxing, euphoric body high that has kept it at the top of evening-smoking lineups for years. The effect settles in with a dreamy mental lift before spreading into full-body calm, making it especially well suited to switching off, easing stress, and sinking into serious comfort. Flowering in around 55-65 days, plants stay compact indoors at around 100 cm and can yield up to 600 g/m2, while outdoor plants may reach 180 cm and produce as much as 1000 g per plant by the second to third week of October. Responsive to LST and topping, but worth watching closely for humidity late in bloom due to its dense flower structure, GrandDaddy Purple remains a standout choice for growers seeking heavy resin, bold purple colour, and one of the most famous grape-forward indicas ever created.
