Fast Buds Company Description

Guava Runtz Auto is a next-generation autoflower built from two proven winners.

On one side, our Guava Auto RF3: a fully stabilized line and champion of the latest Autoflower World Cup. On the other, Mango Runtz (Mephisto Genetics): a multiple award-winning hybrid known for its terpene quality and a very compact structure.

The goal behind this cross was to bring both together, elite performance and terpene expression in a single F1 hybrid. From early testing, the line shows strong hybrid vigor, combining the manageable structure of Mango Runtz with the added strength, freshness and growth energy of Guava RF3.

The terpene profile is intense and forward, tropical fruit, sweet candy notes, and a deep, layered aroma that translates well from flower to final product, with strong bag appeal. In terms of expression, the line shows two main phenotypes. Both carry very similar terpene profiles, one leaning toward deep black coloration, the other staying more green with dark tones developing toward the end of the cycle. Both are vigorous, with dense bud formation and consistent structure across the population.

Guava Runtz Auto was created for growers looking to work with something at the front edge of modern autoflower breeding, combining stability, terpene depth, and performance in one line.
