Radical Auto Feminized Seeds by Absolute Cannabis Seeds – High-Yield Autoflowering Hybrid with Cheese & Haze Genetics

Radical Auto is a high-yield, autoflowering feminized seed from Absolute Cannabis Seeds that delivers massive harvests in record time—no light cycle tricks, no stress, just pure performance.

Still stuck with slow, finicky photoperiods that need constant babysitting? Or worse—autoflowers that barely give you a handful of buds? You’re not alone. Most growers waste cycles on underperforming plants that look great on paper but crash in real life.

But what if you could grow a plant that’s ready in 70 days, hits 1.80 m (5.91 ft) outdoors, and packs dense, resin-coated buds with a sweet, cheesy kick? Radical Auto isn’t just another auto—it’s a yield monster with attitude, bred for those who want serious results without the hassle.

What It’s Like to Use This Plant Solo

Indoors, it stays compact at 80 cm (31.50 in), perfect for stealth grows or small tents. You’ll love how it powers through the cycle in 70–75 days, giving you a solid 500 g/m² (17.64 oz/ft²) with minimal input. It’s the ideal solo project: low drama, high reward.

What It’s Like When You Share the Harvest

Take Radical Auto outside, and it becomes a sharing machine. Reaching up to 1.80 m (5.91 ft) with strong lateral branching, it’s built to impress. Plant it from May to October and you’ll harvest 120–250 g (4.23–8.82 oz) per plant—enough to roll with friends or stash for later. The buds are heavy, sticky, and smell like sweet forest fruit with a sharp cheese finish. Whether you’re passing a joint or packing a bowl, it’s a crowd-pleaser.

How to Grow Radical Auto Seeds

Quick overview: autoflowering · Absolute Cannabis Seeds · 70–75-day cycle · low difficulty · ideal for indoor tents or outdoor gardens.

Safe start: Germinate in a moist paper towel at 22–25 °C. Transplant once the taproot is 1 cm long. For faster rooting, Root Riot Sponges reduce shock and speed up establishment.

Stable seedling: Keep humidity high (60–70%) and light gentle. Water sparingly. Use well-aerated soil to prevent damping off.

Directed growth: Maintain 18–20 hours of light. Avoid overwatering. Use LST to open up canopy. HESI Power Zyme boosts root health and nutrient absorption during rapid growth.

Efficient flowering: Keep RH at 40–50%. Support heavy colas with stakes. Add bloom boosters in week 3–4. No topping—autos can’t recover.

Harvest and refinement: Harvest when trichomes are milky to slightly amber. Flush 7–10 days before. Dry at 18–22 °C and 50–60% RH. Cure for 2–4 weeks to enhance flavor.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Radical Auto in my small greenhouse last summer, and damn—this thing exploded. Planted in a 20L pot with Soil Grow, it hit 1.65 m (5.41 ft) by mid-September. I didn’t top it—just did light LST to spread the canopy. By early October, the colas were thick, dripping with resin, and smelled like a fruit market with a side of aged cheese. I harvested 210 g (7.41 oz) of dense, frosty bud. The high was perfectly balanced: creative in the afternoon, chill by night. I’ve tried dozens of autos, but this one? This is a game-changer.
