Fast Buds Auto #1 is not a showroom cultivar so much as the engine beneath many of the brand's originals. Developed in-house as a stabilized ruderalis-based line, Auto #1 supplies the day-length independence that turns celebrated photoperiod genetics into true autos without stripping away their core character. You can see its fingerprint in releases such as Original Auto Jack Herer, explicitly described as Jack Herer x Fast Buds Auto #1. Because Auto #1 is a working breeding line rather than a retail strain, Fast Buds does not publish terpene charts, THC/CBD ranges, or tasting notes; its job is to stay largely neutral, delivering uniform growth and reliable timing while letting the primary parent lead the flavor and effect. In practice that means compact internodes, early floral initiation, consistent expression across selections, and the brisk seed-to-harvest tempo now typical of modern autos - about nine weeks in representative crosses. Growers value Auto #1 for shortening cycles, improving stress tolerance, and templating a tidy structure that finishes on schedule. You won't find jars labeled "Auto #1," but its contribution runs quietly through Fast Buds' catalog, a proven platform credited to the company's breeding team for pushing autoflower performance forward efficiently, consistently, and without unwanted surprises.
