Guava Runtz Auto charges onto the scene as Fast Buds’ Champions Line debut, an early F1 built from two trophy autos: Guava Auto RF3 - recent Autoflower World Cup champion - and Mango Runtz F5 Auto from Mephisto Genetics, a multiple award-winner. The terpene profile fuses tropical-guava brightness and candy sweetness with a mango-forward twist; think myrcene-driven fruit backed by limonene sparkle and caryophyllene spice. The aroma translates directly to flavor - tropical, sweet, and distinctly mango - while the effect lands squarely in modern-hybrid territory: an upbeat lift and clean euphoria that settles into a smooth, contented calm. Bag appeal is a calling card: dense, frosted flowers with vivid pistils and the kind of stickiness extractors chase. Expect compact, orderly plants with a stout central cola, short lateral branches, and vigorous resin production. Indoors, heights typically sit around 80–120 cm and, in dialed environments, harvests arrive roughly 63–70 days from sprout with productive yields around 450–600 g/m². As a brand-new F1 evaluation line, exact potency figures are still being compiled, but the pedigree points toward high-performance autos. Guava Runtz Auto credits go to Fast Buds, who assembled this cross to merge elite cup genetics with everyday growability and to set a new benchmark for tropical, candy-leaning autoflowers.
