Mendo Frost Auto: two of the strongest autos in one hybrid
Mendo Frost Auto is part of Fast Buds’ new Champions Line and collaboration series. It combines the latest version of Frostbanger Auto, the strongest autoflower tested at the Autoflower World Cup, with Atlas Seed’s Mendo Breath Auto IBL (GMO Auto × Mendo Auto), the top lab-tested strain at the American Autoflower Cup. It’s an F1 hybrid, 60% indica and 40% sativa, with 26–31% THC according to Fast Buds.
A frost and resin factory
Atlas Seed supplied its Mendo Breath Auto IBL seeds, normally unavailable to the public, and Fast Buds selected elite plants as donors to cross with the best Frostbanger specimens. Early observations show strong hybrid vigour, XL-size plants and dense, compact, extremely resinous flowers. It reaches 70–120 cm and yields 500–600 g/m² indoors and 80–220 g per plant outdoors. Harvest time: 9–10 weeks, according to the bank.
Aroma, flavour and effect
A fresh, sweet and spicy profile, with the intense character of both parents.
Its indica dominance steers the effect towards physical relaxation. Growers mostly report deep relaxation and good mood, with the munchies and some sleepiness towards the end, after a slightly upbeat, creative start. An evening profile for unwinding.

Growing tips
Like all autoflowers, Mendo Frost Auto switches to flowering on its own, with no change in light schedule. Sow it straight into its final pot to avoid transplant stress, give it 18–20 hours of light indoors and start feeding at gentle doses. For week-by-week doses, see our Grotek feed chart for autoflowers.
