Hulkberry Auto is Royal Queen Seeds’ revved-up version of Bruce Banner #3 Auto, and one of the strongest autoflowers in their catalog. The goal was simple: keep the raw power of Bruce Banner while adding a rich, pleasant terpene profile.
RQS started with a cross of Ghost OG and Strawberry Diesel, liked what it saw in aroma and strength, and then brought in Diesel Auto for its fast flowering and solid potency. The result, HulkBerry x Diesel Auto, settled into a stable 65% sativa, 30% indica, 5% ruderalis line.
She is fast. From germination to harvest takes only 55–65 days (8–9 weeks), with no need to flip lights to 12/12. Plants stay at 3 to 4 feet (91–122 cm) indoors and outdoors, which keeps grows discreet.
Indoor yields reach 16 to 19 oz/m² (455–540 g/m²), while outdoor plants return 3 to 5 oz/plant (85–140 g/plant).
Flavor and Effects: A Daytime Powerhouse
Open the jar and you will catch spice, earth and ripe strawberry. On the inhale, citrus and diesel take over with woody undertones, and the finish turns fruity. Royal Queen Seeds names limonene, linalool and myrcene as her leading terpenes.
With THC up to 21%, she outperforms plenty of photoperiod strains. A bong bowl or a vape session sends a wave of euphoria through the mind, followed by alertness, motivation and a strong creative spark.
That makes Hulkberry Auto a natural daytime pick: pair her with music, a film or a creative project, or start the morning with her and a cup of coffee for an energizing jolt.
Growing Hulkberry Auto Seeds
Hulkberry Auto is easy to grow, small and rewarding, so beginners can approach her with confidence. Sow directly into the final pot, keep the lights at 18/6 or 20/4 and let her autoflowering genetics handle the timing.
Flowering takes 45–55 days. Light LST during the first weeks spreads her canopy and lifts yields. Outdoors, her quick cycle allows multiple harvests per season in regions with long, warm summers.
