HulkBerry Automatic by Royal Queen Seeds – Fast, Potent & Easy-to-Grow Autoflower

HulkBerry Automatic by Royal Queen Seeds is a high-THC autoflowering strain that delivers a powerful, uplifting high in just 9 weeks from seed to harvest, making it perfect for fast, reliable grows with minimal effort.

Are you tired of waiting months just to enjoy your own homegrown bud? Growing cannabis often feels like a long, complicated journey that eats up your time and energy. You start strong, but then life gets in the way—watering schedules, light changes, nutrient mixes—and before you know it, your plants are stressed, your yields suffer, or you lose motivation altogether.

That constant back-and-forth drains the joy out of growing. You end up with mediocre results, wasted time, or even abandoned plants. The dream of a fresh, personal harvest turns into just another chore you keep postponing.

HulkBerry Automatic changes that. With its rapid 65–70 day cycle, this sativa-dominant autoflower skips the stress and delivers big, frosty yields fast—no complicated routines, no guesswork. Just plant, feed, and harvest high-quality bud in under 10 weeks.

How HulkBerry Automatic speeds up your grow from start to harvest

This strain cuts out the waiting and guesswork. With stable genetics and a short life cycle, it moves quickly from seedling to flowering without needing light cycle changes. That means no veg phase planning, no topping stress, and no months of daily maintenance.

Its compact size—rarely exceeding 1.10 m (3.61 ft)—makes it ideal for small spaces or stealth grows. You don’t need to train it heavily or manage stretch. Just give it consistent light (18–20 hours daily), and it’ll do the rest.

Simple steps to grow HulkBerry Automatic without wasting a minute

1. Soak seeds for 4–12 hours or use the paper towel method for faster germination.
2. Plant directly into a 20 L (5.3 gal) final pot to avoid transplant stress.
3. Keep lights on 18–20 hours daily—no switching needed.
4. Water when the top inch of soil feels dry; avoid overwatering.
5. Harvest after 9 weeks when trichomes turn milky to amber.

How to grow HulkBerry Automatic seeds

Quick overview: Royal Queen Seeds’ HulkBerry Automatic is a low-difficulty autoflower with a 65–70 day cycle, ideal for indoor closets or outdoor patios in temperate climates.

Safe start: Germinate seeds in a moist paper towel at 22–25 °C. Transplant once the taproot is 1 cm long. For a hassle-free start, Clon Fix strengthens roots and reduces shock.

Stable seedling: Use a well-aerated soil mix with perlite. Keep humidity high (60–70%) and light gentle. Water lightly every 2–3 days.

Directed growth: Maintain 18–20 hours of light daily. Use a 20 L (5.3 gal) pot from the start. Apply Top Max BioBizz weekly to support strong branching and resin production.

Flowering by stages: RH should drop to 40–50% in mid-flower. Support heavy colas with stakes. Avoid aggressive pruning—this auto recovers slowly.

Harvest, drying and curing: Harvest when 70% of trichomes are milky, 30% amber for a balanced high. Flush 7 days before harvest. Dry at 18–22 °C and 50–60% RH for 10–14 days, then cure in jars for 2–4 weeks.

Personal Experience of Pevgrow’s CEO (Alan)

I grew HulkBerry Automatic in my small urban setup—a 0.80 x 0.80 m tent with a 250W LED. I planted three seeds directly into 20 L pots and kept the light on 18/6 the whole time. No topping, no SCROG—just clean, simple growing. By week 8, the trichomes were milky with a few amber hints, and the smell was unreal: sweet diesel and ripe berries. I flushed for 7 days, dried slowly, and cured for three weeks. The high was exactly what I needed—clear, energizing, perfect for creative work. I’ve tried dozens of autos, but this one stands out for speed, potency, and ease. If you’re short on time but want quality, this is your strain.
