Guava Auto™ by FastBuds – Sweet Tropical Flavor, High Yield & Fast Harvest

Guava Auto™ by FastBuds is a powerhouse autoflower that delivers up to 550 g/m² of dense, trichome-coated buds in just 8–9 weeks, combining sweet tropical flavor with exceptional resilience and beginner-friendly growth.

Are you tired of waiting months just to harvest a few lackluster buds?

Most autoflowers make you choose: fast harvest or big yields. High potency or easy growing. Tropical flavor or mold resistance. You end up compromising on what matters—your time, your yield, and your smoke.

What if every plant delivered maximum resin, explosive flavor, and harvest-ready buds in under 9 weeks—without needing a PhD in botany?

Imagine your tent filled with XL-sized plants dripping in trichomes, smelling like fresh guava punch, and finishing so fast you can run multiple cycles a year. No more worrying about powdery mildew during humid weeks or losing plants to pests. No more struggling with finicky genetics that demand perfect conditions.

Guava Auto™ delivers all that—and more—thanks to its elite F3 polyhybrid genetics

Bred from Gorilla Cookies Auto, Kosher Cake, and Tropicana Cookies Auto, this 50/50 hybrid thrives in any setup—indoors, outdoors, or in a greenhouse. It laughs at mold, laughs at pests, and laughs at beginners who think they can’t grow like pros. Whether you're after top-shelf rosin or a daily smoke that uplifts without locking you to the couch, Guava Auto™ is your new go-to.

Forget average yields and bland flavors. Guava Auto™ redefines what autoflowering means: fast, fearless, and freakishly productive. It doesn’t just survive—it dominates.

How to grow Guava Auto™ for maximum results

Guava Auto™ thrives with minimal intervention, but a few smart moves unlock its full potential. Start in a final pot of 18–27 L to avoid transplant stress. Use a well-aerated soil or coco mix—Light Mix BioBizz is a perfect match for strong root development. Keep light at 18–20 hours daily throughout the cycle. Low-stress training (LST) works well, but avoid topping—this autoflower prefers a natural structure.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Guava Auto™ side-by-side with Gorilla Cookies Auto, and the difference was clear. Guava hit faster, smelled like a fruit stand, and produced stickier buds with way less effort. I didn’t top or train—just let it go—and still got 510 g/m² in my 600W LED tent. The high? Smooth, functional, and perfect for daytime. No paranoia, no couch-lock—just pure joy. I’ve recommended it to three friends already, and all of them are growing it again. If you want a strain that delivers on every promise, this is it.
