Critical Kush Auto by Barneys Farm – 22% THC Indica-Dominant Autoflowering Seeds

Critical Kush Auto by Barneys Farm is a hard-hitting, indica-dominant autoflowering strain with 22% THC, delivering intense relaxation and dense, resin-coated buds in just 8–9 weeks from seed to harvest.

Struggling to unwind after a long day? You’re not alone. Many growers chase that deep, full-body calm but end up with weak yields or finicky plants that demand constant attention. The reality? Most so-called "easy" strains still need pruning, perfect conditions, and weeks of patience — and even then, the high can be underwhelming or too cerebral to truly melt stress away.

Now imagine a plant that grows strong on its own, fills your space with earthy pine aroma, and rewards you with heavy, kush-dense colas that knock out tension in one hit. No training needed. No light cycle changes. Just plant, feed, and harvest top-shelf relaxation in under two months. That’s Critical Kush Auto — the no-nonsense solution for indica lovers who want power, purity, and peace without the hassle.

It’s not just fast — it’s forgiving, resilient, and packed with the terps and THC that make kush a classic. Whether you're managing stress, chasing sleep, or just want a smooth end to your day, this strain gets you there without compromise.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Critical Kush Auto stands out for its raw power and simplicity. I ran three plants in my 1.20 m² (12.92 ft²) tent under a 600W LED, 20/4, in 25L pots with living soil. No topping, no fancy tricks — just consistent watering and a solid bloom booster. By week 8, the smell was unmistakable: pungent, hashy, with that classic kush punch. The buds were rock-hard, dripping with resin, and after a 10-day flush and 3-week cure, the high was exactly what I wanted — deep, full-body relaxation with a gentle cerebral lift. Perfect for unwinding after a long week. If you're looking for a no-fail indica auto that delivers on every level, this is it.
