Banana Guava Auto by FastBuds Seeds

Banana Guava Auto Seeds

Banana Guava Auto is an F1 feminized autoflower built around two award-winning parent lines. Guava Auto RF3 took 1st Place Best Sativa, while Banana Jealousy Auto took 1st Place Best Indica at the same Autoflower World Cup.

FastBuds Seeds developed this Champions Line hybrid to combine tropical character, potency, creamy depth, plant structure, and resin production.

The genetics are Guava Auto RF3 x Banana Jealousy RF3, with a 65% Indica and 35% Sativa profile. Plants reach 80–120 cm (31–47 inches) and finish in around 9–10 weeks.

This Autoflowering release is still an early F1 undergoing in-house evaluation. That makes it especially interesting if you want bold effects, expressive aroma, memorable flavor, and access to a ground-floor breeding project. We really like this strain because it takes two proven competition directions and throws them into one fresh genetic collision.

It also belongs among the 2026 new strains worth watching if modern autoflower genetics are your thing.

Flavor And Effects Turn Tropical Character Into A Heavy-Hitting Experience

The flavor starts with banana and guava, then slides into cream and mixed fruit. It feels like a tropical fruit stand crashed straight into a bowl of banana custard. The guava brings an exotic edge, while the creamy banana side smooths everything out. You get sweetness, ripe fruit, and a softer finish instead of a one-note candy profile.

We think that contrast is the real attraction. Banana Guava Auto does not rely on fruit alone. The creamy depth gives the tropical profile more weight and makes each pull feel richer. It sounds simple on paper. In practice, the combination has much more personality.

The breeder describes the project around energy and potency while aiming for a balanced hybrid expression. With THC reaching up to 28%, the experience is positioned on the strong side rather than the gentle side. The Sativa influence brings the energetic part of the equation, while the Indica-dominant genetic balance adds depth.

Think of the effects as a bright current running through the mind while a heavier tide settles through the body. It is that push-and-pull character that makes the cross interesting. You are not buying another anonymous fruity auto. You are getting an early F1 built from two award-winning directions with very different personalities.

Want tropical flavor with some muscle behind it? We think this one makes a convincing case.
