Granddaddy Purple Auto by Royal Queen Seeds is the autoflowering rendition of the California classic, created from Granddaddy Purple x Big Bud Auto. The line is indica-dominant (75% indica, 20% sativa, 5% ruderalis) and tests around 19% THC. Plants stay manageable, reaching roughly 60–120 cm indoors and up to about 150 cm outside. Under good conditions, yields average 375–450 g/m². Bloom takes 55–60 days, with harvest typically 70–85 days from germination, suiting quick indoor cycles or seasonal outdoor runs. Aromas lean toward blueberry and mixed fruit with herbal and pine notes. Reported effects are physically relaxing with sleepy, uplifting overtones. Seeds are feminized autoflowers intended for straightforward cultivation. Suitable for indoor and outdoor grows across long-summer climates.
