Guava Sundae Auto – Fast Buds

Guava Sundae Auto from the Fast Bud Company is arguably one of the very best autoflowering strains. This cross between Guava Auto RF3 and Sundae Thumper F4 represents a modern breeding strategy in which award-winning autoflowering genetics have been combined to create high-yielding hybrids. Guava Auto RF3 was the overall winner of the Autoflower World Cup, and Sundae Thumper F4 from Mephisto Genetics was named the best autoflower hybrid at the American Autoflower Cup 2025.

Even in the early stages of development, Guava Sundae Auto displays vigorous growth – the plants grow compact to medium-sized, developing a bushy structure and very strong side shoots. The strain responds well to training methods such as LST or leaf management. Guava Sundae Auto is highly aromatic, with an intensely fruity scent – a delicious blend of guava with creamy notes of gelato. It is a well-balanced hybrid with a distinctive aroma, high quality and modern genetics, appealing particularly to discerning growers.

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.

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.
