Mango Frost Auto

If you follow the bank's recent releases, the names will ring a bell. The Mango Cherry Runtz uses the Mango Runtz; the Mendo Frost uses the Frostbanger. This cross brings those two together directly, with no intermediaries.

Autoflower World Cup 2026 Winner

The pedigree came built in. Mephisto Genetics' Mango Runtz F5 Auto was Best New Autoflower 2025 at the Autoflower World Cup, and the house's own Frostbanger Auto took the Most Potent Autoflower title in that same edition.

Putting them together paid off: Mango Frost Auto won the Autoflower World Cup 2026. It's an uncommon fact on a seed sheet, because most varieties sell on their parents' awards, not their own.

65% Sativa, but 70 to 110 cm

The genetics declare 65% sativa, which normally suggests a tall plant. Not this one. Fast Buds explains it with a phrase that describes what it does well: it channels energy into producing rather than stretching. It stays between 70 and 110 cm, with flowers stacking from the start of flowering in compact, robust colas.

They're dense, very sticky buds, built to weigh, which gives it a yield of 450–550 g/m² indoors and between 60 and 180 grams per plant outdoors. All of this in eight weeks from seed, which for a sativa-dominant strain with up to 30% THC is quick. Among autoflowering seeds, it's one of the best for making the most of a small space.

Mango first, cream and petrol after

The flavour profile has a clear journey and it's worth following it in order: it starts with sweet mango, bright and tropical, and as it develops a base of cream and petrol emerges with a tangy note at the end. It's not a linear sweetness: there's contrast between the top and the depth.

A practical note on the smell, because the bank insists on it: the aroma is intense and persistent, and fills the room easily. If you're growing at home and discretion matters, factor in that you'll need a carbon filter from the start of flowering, not halfway through.
