Mendo Frost Auto

Mendo Frost Auto is a resin-focused FastBuds release from the Champions Line and Collaboration Series, made as feminised autoflowering seeds. The cross is exact and worth knowing: Frostbanger Auto F4 x Mendo Breath Auto IBL, with Mendo Breath Auto IBL coming from GMO Auto x Mendo Auto.

FastBuds built this early F1 hybrid around two proven autoflower lines. Frostbanger Auto was the strongest autoflower tested at the Autoflower World Cup, while Atlas Seed’s Mendo Breath Auto IBL was the top-performing strain in laboratory testing at the American Autoflower Cup in California. Atlas supplied Mendo Breath Auto IBL seeds, normally not available to the public, and FastBuds selected elite Mendo Breath IBL donors to cross with the best plants from the latest Frostbanger generation.

The numbers are strong without needing much dressing up. Mendo Frost Auto is listed at 26–31% THC with CBD below 1%. The genetic balance is 40% sativa and 60% indica, so it keeps a true hybrid profile while leaning slightly to the indica side.

FastBuds describes the early observations as vigorous, XL-sized plants with dense, compact flowers and very heavy frost. Expect a plant height of around 70–120 cm, with indoor, outdoor, greenhouse and mixed-light setups all listed as suitable rooms. The flowering time is 9–10 weeks, which keeps it in familiar modern auto timing rather than stretching into a long project.

Yield figures are also substantial for an autoflower. Indoors, FastBuds gives 500–600 g/m². Outdoors, the stated harvest is 80–220 g per plant. The intended climate range is broad, covering very hot, hot, moderate, cold and very cold conditions, although the plant is still described as an indoor, outdoor, greenhouse and mixed-light option rather than tied to one narrow style of cultivation.

Aroma strength is marked as strong, and the flavour profile is given as fresh, spicy and sweet. That should suit customers who like modern resin-heavy autos with more going on than plain sweetness, especially if dense flowers and a sugar-coated finish are part of the appeal.

Mendo Frost Auto is best understood as an early collaboration release built around potency, resin and award-tested autoflower parent lines. It’s a good fit if you want a compact-to-XL automatic with serious frost, sweet-spicy flavour and a clear breeding story behind it.
