Are you tired of waiting months just to enjoy a smooth, flavorful smoke?

Most autoflowers sacrifice taste and potency for speed, leaving you with bland buds and weak effects. You invest time, space, and nutrients, only to end up with something that doesn’t hit right or smell special.

What if your plants kept failing because of small mistakes or unstable conditions?

Beginner growers often struggle with sensitive strains that demand perfect pH, lighting, and feeding. One wrong move and your yield crashes. The stress kills the joy — and your stash stays empty. You start wondering if growing is even worth it.

This isn’t just another auto — it’s a fusion of legendary OG Kush, sweet Bubble Gum, and high-yielding Critical Automatic. You get a plant that forgives mistakes, laughs off temperature swings, and still packs dense, resinous buds with a deliciously sweet and earthy profile. Ready in 10–11 weeks, it’s perfect for stealth setups, small spaces, or anyone who values consistency over complexity.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autoflowers, but Bubble Kush Automatic stands out for its consistency. I grew it in a 60x60x160 cm tent with a 300W LED, 18/20 light cycle, and a 20L final pot. No topping, no fancy techniques — just solid basics. At week 10, I harvested 380 g/m² of dense, trichome-covered buds with a killer bubblegum punch. The high is smooth, relaxing, and perfect for unwinding. What I love most? It forgave my late watering and still outperformed photoperiods I’ve grown. For the price, it’s a no-brainer — especially if you want flavor, ease, and reliability in one package.
