Auto Blue Dream 00 Seeds · High-THC Autoflowering Strain for Easy Growing & Big Yields

Auto Blue Dream from 00 Seeds is a high-THC autoflowering strain that delivers massive yields of vibrant, resinous buds in just 70–80 days from seed to harvest—no light cycle changes needed.

Still struggling with slow, low-yielding plants?

Are you tired of waiting months just to harvest a handful of airy buds? Or worse—dealing with weak plants that can’t handle a little stress or fluctuating weather?

What if you could grow a legendary sativa hybrid without the hassle?

Imagine harvesting dense, purple-tinged colas with a rich citrus and caramel aroma—without needing expert skills or perfect conditions. Most photoperiod strains take 12+ weeks, demand precise light control, and punish mistakes hard. But they also offer top-tier flavor and potency… if you’re willing to wait.

Auto Blue Dream is your shortcut to premium genetics—without the wait

This autoflowering version of the iconic Blue Dream combines the best of Super Silver Haze and Blueberry, crossed with a robust ruderalis. You get a balanced high—energizing at first, then deeply relaxing—with minimal effort. It grows fast, resists stress, and thrives both indoors and outdoors, making it perfect for discreet or beginner-friendly grows.

Why Auto Blue Dream outperforms your current strain

Forget finicky plants that demand constant attention. Auto Blue Dream is built for real-world conditions—whether you're growing in a closet or a backyard. It adapts quickly, recovers from stress, and delivers consistent results, even in less-than-ideal environments. Plus, you’ll save weeks compared to traditional strains, with harvests possible every two months in warm climates.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Auto Blue Dream from 00 Seeds stands out. I used to stick to photoperiods because autos felt weak or flavorless. But this one? It hits like a sativa, smells like a dispensary, and finishes before my old strains even start flowering. I grew it in a 20L pot with Micro Kit Ata Terra and a Zeus LED—no fancy inputs. By day 75, I had dense, frosty colas with purple hues. The high was perfect: creative in the morning, chill by night. I’ve recommended it to friends who’ve never grown before—and they all harvested successfully. If you want a strain that delivers on every level without the fuss, this is it.
