Granddaddy Purple is an autoflowering feminised seed from Double Seeds, bringing together the large, densely packed buds of Big Bud with the striking violet tones of Purple Urkle. Plants are expected to produce oversized flowers with a glittering finish in deep purple shades, offering a grape-led bouquet with a fruity berry flavour on the palate. Its predominantly indica nature points to a settled, mellow experience, with effects described as euphoric at first and relaxing afterwards. Flowering takes roughly nine weeks from seed, which suits growers wanting a compact, fast-moving cycle. Because it flowers automatically rather than relying on a change in light period, it can fit into a variety of grow setups. THC is listed between 20 and 23 percent. Whether you are after eye-catching colour or a flavourful, easygoing smoke, this strain is a rewarding addition to any collection.
