Is it more potent than the Guava RF3?

This strain is currently being tested; however, Banana Jealousy RF3 frequently tests at 28% THC, and Guava RF3 at around 30% THC, giving you a good idea of what to expect. But that’s not the main feature; the terpene profile is to die for, and it’s the main reason Banana Guava Auto will win you over.

I love the idea. Will you have more crosses like this with top strains?

Yes, this strain, and others coming soon, will be part of the “Champions” line, featuring exclusive crosses made only with award‑winning strains.

Since it’s F1, what nutrient schedule works best?

F1 simply means it’s the first generation of the strain and has nothing to do with nutrient requirements. You can feed it just like you would any other autoflowering strain.

What to expect from an RF3 x RF3 cross?

Both Guava RF3 and Banana Jealousy RF3 are exclusive genetic lines that have undergone extensive selection. By crossing two strains that have been so carefully developed, you can expect a combination of the best traits from both, taken to their fullest expression.

What made you choose to cross it with Banana Jealousy RF3?

The Banana Jealousy RF3 complements our Guava RF3 beautifully. It’s easy to grow, thrives in virtually any environment, offers up to +28% THC, and delivers a lot of flavor, all qualities that perfectly align with our goals with the Guava RF3 line. On top of that, Banana Jealousy RF3 is an outstanding strain that has won 1st place for Best Indica at the Autoflower World Cup and 3rd place for Strain of the Year (Autoflower) in the NASC Grower’s Choice Awards 2025.

Description

Banana Guava Auto joins our new Champions Line, a breeding project dedicated to combining the most awarded autoflower genetics into next generation hybrids built for real performance. This F1 cross brings together two category winners from the same Autoflower World Cup: Guava Auto RF3, 1st Place Best Sativa, and Banana Jealousy Auto (Banana Jealousy x Banana Daddy Auto) by Ethos Genetics, 1st Place Best Indica.

The goal behind this project was to merge the energy, potency, and exotic tropical profile of Guava with the creamy depth, structure, and resin production of Banana Jealousy, creating a balanced champion hybrid that delivers the best of both worlds.

This is an early F1 release. Seeds have passed our strict germination standards and are currently undergoing in-house evaluation. Banana Guava Auto is designed for growers looking for elite genetics, modern terpene expression, and the opportunity to work with a ground-floor Champions Line project. Two category winners. One performance driven hybrid.
