Guava Auto RF3™ represents the further refinement of Fast Buds' Guava Auto line. According to Fast Buds, the RF3 version was developed through repeated selection over eight generations, with the objective of improving genetic stability, uniformity, plant structure, terpene expression and resin production. The company describes the result as a more consistent expression of its Guava genetics, with tighter structure and denser flowers.
The defining feature of this variety is its terpene profile. Fast Buds describes it as a richer and sweeter guava profile layered with creamy fruit characteristics, creating an unmistakably tropical and dessert-like aromatic impression. The aroma is designed to be particularly pronounced, while the dense flowers are covered with abundant trichomes, giving the variety strong visual and resin appeal.
The genetic background is particularly interesting: Fast Buds' own phenotyping account explains that the original project involved a combination of Gorilla Cookies, Kosher Cake and Tropicana Cookies autos, from which unusual and distinctive phenotypes were selected through successive generations. The company ultimately focused on a particularly distinctive Guava expression and continued refining it into the RF3 line.
