Red Gorilla Girl XL Auto® by Sweet Seeds is a high-THC autoflowering powerhouse that delivers dense, resin-coated buds with a sweet citrus and cypress aroma in just 8–9 weeks from seed to harvest—no waiting, no stress, just premium results.

Feeling like your autoflowers never hit hard enough or take too long to finish?

You’re not alone. Most autos promise big but end up delivering mediocre yields, weak effects, or buds that look more sad than spectacular. And when you’re juggling life, work, and your grow, waiting 10+ weeks for a lackluster harvest just isn’t worth it. You end up losing motivation, wasting space, or worse—quitting altogether.

That’s where Red Gorilla Girl XL Auto® steps in. This isn’t just another autoflower—it’s a precision-engineered strain from Sweet Seeds’ Red Family, built to deliver maximum impact in minimal time. With up to 21% THC, explosive flavor, and buds so resinous they glitter, it turns your grow from a chore into a celebration. And with 85% of plants developing stunning purple hues, it’s as eye-catching as it is potent.

Dense, Resinous Buds Ready in Just 9 Weeks

Red Gorilla Girl XL Auto® cuts the wait without cutting corners. From germination to harvest, you’re looking at just 8–9 weeks—ideal for quick turnarounds, stealth grows, or stacking harvests back-to-back. Indoors, expect up to 550 g/m² (1.94 lb/ft²); outdoors, each plant can yield up to 125 g (4.41 oz), even in less-than-ideal conditions. The buds are large, compact, and drenched in trichomes, making them perfect for smoking, vaping, or extracting.

How to Grow Red Gorilla Girl XL Auto® for Maximum Yield

Starting strong means setting the right foundation. This strain thrives in a light, well-aerated medium—whether soil, coco, or hydro—and prefers a final pot size of 18–27 L (6.76–10.20 gal) to support its vigorous growth. Because it’s an autoflower, keep the light cycle at 18–20 hours daily from start to finish. Avoid aggressive pruning; instead, use gentle LST (low-stress training) early on to open up the canopy and boost light penetration.

1. Germinate seeds in a moist, dark environment at 22–25 °C (71.6–77 °F).
2. Transplant carefully once the taproot is ~1 cm (0.39 in) long.
3. Use a balanced root booster like Startrex BioTabs to strengthen early development.
4. Maintain pH between 6.0–6.5 (soil) or 5.8–6.2 (coco/hydro) throughout the cycle.
5. Boost flowering with a quality PK enhancer like Brutal Bloom during weeks 4–7.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Red Gorilla Girl XL Auto® in my small balcony setup last summer—just 3 plants in 20 L pots under natural light. Even with inconsistent watering and a heatwave, they thrived. The buds were rock-hard, shimmering with trichomes, and smelled like lemon candy and forest air. I waited until most trichomes turned milky-amber, dried slowly at 18 °C (64.4 °F), and cured for three weeks. The result? One of the smoothest, most flavorful smokes I’ve had all year. It’s now my go-to for quick, high-quality harvests when I don’t have time to babysit photoperiods. If you want power, beauty, and speed in one strain, this is it.
