HulkBerry Auto is Royal Queen Seeds’ autoflowering, sativa‑dominant Feminised cross of Hulkberry × Diesel Auto that aims to combine lively daytime effects with a pronounced fruity/diesel flavour. The breeder lists this as roughly 65% sativa, with THC levels reported up to 21% and CBD described as low. Flowering is given as 45–55 days, with plants commonly ready to harvest about 55–65 days after germination.
Royal Queen Seeds documents HulkBerry Auto’s terpene profile as particularly high in limonene, linalool and myrcene, producing citrus, fruity and diesel flavour impressions on inhalation. Commonly reported effects from the breeder and grower community emphasise clear‑minded, uplifting and energising characteristics, making it a daytime choice for creative or social activities.
Cultivation notes from the breeder describe HulkBerry Auto as easy to grow and compact (rarely exceeding c.100 cm indoors), with high indoor yields when grown under controlled conditions and modest outdoor production. Reported indoor yields centre around 450–500 g/m² while typical outdoor single‑plant yields are substantially lower (approx. 80–150 g/plant according to breeder entries). The variety is sold and documented by Royal Queen Seeds and the breeder pages and grow guides provide the primary dataset for genetics, cannabinoids, terpene profile and timing.
