Guava Runtz Auto – Fast Buds

Guava Runtz Auto from 420 Fast Buds Company launches the new ‘Champions Line’ – a breeding project aimed at integrating award-winning cannabis genetics into modern autoflowering strains. This F1 hybrid combines the Guava Auto RF3 strain, a winner of the Autoflower World Cup, with the Mango Runtz F5 Auto from Mephisto Genetics. This blend is undoubtedly a very potent strain, combining Fast Buds’ in-house stability with elite external breeding. Guava Runtz Automatic displays excellent hybrid vigour with a compact growth habit; it is extremely easy to grow and is primarily aimed at growers seeking access to modern, innovative genetics who value quality, stability and exceptional terpene profiles.

The strain brings together two intense flavours: Guava Auto provides tropical fruity notes, stable autoflowering characteristics and high yields, whilst Mango Runtz F5 Auto adds extra depth to the terpene profile thanks to its complex lineage. The result is an expressive aroma with hints of guava, sweet mango and creamy notes of candy, accompanied by a dense coating and high visual quality.

420 Fastbuds Autoflower Seeds with CBD, FF, and Selected Feminized Releases

420 Fastbuds is best known for autoflower seeds shaped by California-inspired strain families and a breeder identity that Cannapot connects to Los Angeles roots and later development in Spain. The range is built around familiar names such as Afghan Kush, Girl Scout Cookies, Gelato, Bruce Banner, Sour Diesel, and other modern lines that give a clear direction from the start.

Autoflowers are the strongest part of the breeder lineup, but the range is not limited to one format. Alongside the main auto selection, there are CBD autos, FF lines, RF3 releases, and selected feminized entries while keeping the Fast Buds identity clear.

Quick Facts

The lineup is easiest to read by starting with the autoflower core, then moving into the dedicated CBD seeds side, the FF branch, and the selected feminized releases. That makes it easier to compare the main Fast Buds direction with the broader options that now sit alongside it, including the wider autoflower seeds category.
