Auto Blueberry® by Dutch Passion – Fast, Fruity Autoflower with Legendary Blueberry Flavor

Auto Blueberry® by Dutch Passion is a fast, compact autoflowering strain that brings the legendary Blueberry taste and relaxing indica effects to growers of all levels, ready from seed to harvest in just 8–10 weeks.

Is your grow space full of chaos and missed potential?

Let’s face it — most autoflowers either take forever or deliver bland buds with zero character. You want something fast, but not basic. You want flavor, power, and ease — all in one plant. But too often, you end up with weak yields, stretchy stems, or flowers that smell like hay instead of heaven.

Why waste months on slow strains when you can harvest in 2?

Waiting 12+ weeks for a photoperiod strain? That’s old school. And if your current autoflower lacks potency or aroma, you’re just going through the motions. Time lost, space wasted, and no real reward. Plus, inconsistent phenotypes mean you never know what you’ll get — weak, airy buds or a plant that barely flowers. That frustration kills the joy of growing.

Auto Blueberry® delivers legendary flavor, fast and fuss-free

Meet the autoflower that actually tastes like blueberry. Thanks to authentic genetics from Dutch Passion’s archive — originally developed with DJ Short himself — Auto Blueberry® gives you a true-to-name fruity punch in record time. It grows compact (0.50–0.75 m), finishes in 8–10 weeks, and produces frosty, dense buds rich in terpenes (up to 1.15%). No guesswork, no fuss — just consistent, high-quality results with minimal effort.

What your harvest will look like with Auto Blueberry®

Imagine opening your tent to a sweet, berry-laced aroma that hits you before you even see the buds. Your plant stays short and bushy, perfect for stealth grows or small spaces. The main cola dominates, with a few strong side branches — ideal for SOG setups. Buds swell fast, turning dense and rock-hard, often developing deep purple hues under cooler night temps. By week 10, you’re looking at a trichome-covered masterpiece that smells like a fresh fruit market and hits like a premium indica.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autoflowers, but Auto Blueberry® still stands out. I ran two plants in 30L AirPots under a 200W LED with a 20/4 cycle. By week 8, the smell was unreal — like walking into a bakery full of blueberry muffins. I used BioTabs and added Bud Factor X in week 5. Harvested at week 10, I got 43g and 30g of frosty, dense buds. The high is deep and relaxing — perfect for unwinding. My pro tip? Drop night temps to 16°C in late flowering to boost purple colors and resin production. This one’s a keeper.
