Guava Sundae Auto

Guava Sundae Auto is built around two award-winning parent lines: Guava Auto RF3 × Sundae Thumper F4. FastBuds has paired a World Cup-winning Guava Auto RF3 with Sundae Thumper from Mephisto Genetics, noted as an American Cup champion, to make a loud, modern F1 autoflower with plenty of terp character.

It’s available as feminised autoflowering seeds and carries a balanced 50% sativa / 50% indica profile. THC is listed at 26–30%, with CBD below 1%, so this is clearly aimed at shoppers after a stronger contemporary auto rather than a mild, low-THC option.

The plant itself is described as large and tall for an autoflower, with strong hybrid vigour and a solid, consistent frame across the population. Height is given at 70–120 cm, with an XXL size rating. FastBuds points to dense stacking and well-balanced internodal spacing, with the line bred for structure, yield potential and terpene performance in the same run.

Flowering time is 8–9 weeks. It can be run indoors, outdoors, in a greenhouse or under mixed lighting, and the intended climate range includes very hot, hot and moderate conditions. Indoor harvests are listed at 450–600 g/m², while outdoor plants are listed at 60–300 g per plant. The flowers are described as large, heavy and tightly formed, with a clean, uniform finish.

The flavour is the part that gives Guava Sundae Auto its name. Expect fresh tropical guava up front, followed by a creamier gelato depth. The listed taste notes are fruits, guava and sweet, with a strong smell rating, so it should suit collectors drawn to bold dessert-fruit profiles rather than quiet, earthy autos.
