Granddaddy Purple Auto brings iconic grape-and-berry character to a quick, easygoing grow. Expect dense, resin-rich buds, a soothing indica-leaning profile, and a full life cycle of just 8–10 weeks from germination. It’s a compact, beginner-friendly choice with plenty of personality.
Our breeders developed this autoflower from Purple Urkle, Big Bud, and Ruderalis. The result leans 80% indica and 20% sativa, blending Purple Urkle’s celebrated fruit notes with Big Bud’s robust growth and Ruderalis’ automatic flowering trait.
The aroma layers ripe berries and sweet grape with a rich hashish edge. Floral hints soften the profile, while the finished buds deliver smooth, sweet smoke with a luscious fruit-forward finish.
With THC levels of 16–19%, Granddaddy Purple Auto offers a balanced, medium-strength experience. Expect a happy, focused mood alongside deep physical relaxation. Its calming character makes it a natural evening pick after a demanding day.
Linalool brings a gentle floral note, Valencene adds a bright citrus lift, and Alpha-Pinene contributes a crisp, fresh edge. Camphene rounds out the listed terpene profile. The strain’s generous resin coverage also makes it appealing to growers interested in aromatic flower and concentrates.
These autoflowering seeds begin flowering according to age, without needing a change in light schedule. The full cycle takes about 8–10 weeks, and the hardy, compact plants suit indoor or outdoor gardens. Every Grassfarmer order comes with our germination guarantee for added confidence from the start.
Give seedlings a clean start with quality soil or a well-prepared coco or peat blend, and keep moisture steady without waterlogging the roots. Autoflowers move quickly through each stage, so provide consistent care from the beginning. Indoors, an 18/6 or 20/4 light schedule supports vigorous growth.
Plants can reach around 1.2 m and develop a sturdy main stem with productive side branches. Choose a bright, well-ventilated space and maintain comfortable temperatures. Keep humidity in check, especially as flowering progresses, and monitor plants regularly for pests or signs of stress.
Harvest arrives in just 8–10 weeks from germination. Under strong indoor conditions, yields can reach 400–550 g/m²; outdoor plants may produce around 300 g each. With ample sunlight, good airflow, and steady nutrition, expect firm, trichome-coated buds with vivid berry-and-grape character.
