Guava Sundae Auto Overview

Spec sheet first — strain: hybrid, seed type: autoflower, THC: 19-24%, yield band: medium, environment: indoor or outdoor.

Smell-first: crack a jar of this Fast Buds autoflower and the fruity-sweet wave hits before you even get a good look at the buds. Guava Sundae Auto pulls 400–550 g/m² indoors in roughly 9–10 weeks from seed, which is a solid return for a strain that asks very little from the grower. THC lands in the 19–24% range, making it genuinely potent without chasing an arbitrary number. The genetics come out of Fast Buds' Champions Line breeding project, where they focused on stacking their most decorated autoflower stock into a single, stable package. It runs well indoors or out, handles beginner-level care without punishing small mistakes, and finishes fast enough to squeeze in multiple outdoor cycles per season in most US climates.
