Radical Juice Auto Ripper Seeds – Fruity Autoflowering Indica | Tropicana Cookies x Runtz Cross

Radical Juice Auto by Ripper Seeds is a high-terpene autoflowering indica that delivers a tropical fruit explosion in just 70–75 days from seed to harvest, making it perfect for fast, flavorful, and fuss-free growing.

Feeling like your current autoflower just doesn’t hit the spot? Like it lacks that wow factor in flavor or punch? You’re not alone. Many growers stick with basic strains that deliver average yields and forgettable tastes, missing out on the full sensory experience cannabis can offer.

That lack of excitement can make growing feel like a chore instead of a passion. You invest time and energy, only to end up with bland buds and weak effects. It’s frustrating when your plant doesn’t live up to its potential — and it’s easy to blame yourself, when the real issue is the genetics.

The solution? Radical Juice Auto. This Tropicana Cookies x Runtz cross isn’t just another auto — it’s a terpene powerhouse designed to deliver intense fruity aromas, sticky buds, and a balanced high that keeps you creative and relaxed. With strong mold resistance and a compact structure, it’s built for success, whether you're growing indoors or outdoors.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Radical Juice Auto last summer in my small greenhouse, and it blew me away. I planted three seeds, all germinated, and within 10 weeks I had dense, frosty colas dripping with resin. The smell? Like walking into a candy store mixed with a citrus grove. I used LST early on and gave them HESI Bloom Complex in mid-flower — the buds came out rock-hard. The high is smooth: creative at first, then deeply relaxing. Perfect for evening hangs. My only tip? Don’t top autos — just train gently. This one’s a keeper.
