Mendo Frost Auto is part of our new Champions Line and Collaboration Series, created to bring together the most powerful and award-winning autoflower genetics available today. This early F1 hybrid combines two lab-proven heavyweights: last version of Frostbanger Auto, the strongest autoflower tested at the Autoflower World Cup, and Mendo Breath Auto IBL (GMO Auto x Mendo Auto) from Atlas Seed, the top-performing strain in laboratory testing at the American Autoflower Cup in California.

The idea behind this project was simple, to combine the two most potent autos in the game into one next-generation hybrid. After meeting with the Atlas team and exchanging knowledge about genetics, breeding, and the future of autoflowers, we partnered on this exclusive project. Atlas provided their Mendo Breath Auto IBL seeds, normally not available to the public, and we carried out the selection at our facilities, using elite Mendo Breath IBL plants as donors and crossing them with the best specimens from the latest Frostbanger generation.

This is an early F1 release. Seeds have passed our strict germination standards and are currently undergoing in-house testing. Early observations point to strong hybrid vigor, XL-sized plants, and extremely resinous, sugar-coated flowers with the potential for outstanding potency and bag appeal. Mendo Frost Auto represents our vision for the Champions Line, combining the most awarded genetics and collaborating with top breeders to create new, powerful hybrids that push modern autoflower performance to the next level.
