Her name sums her up perfectly — Fat Banana Auto stinks of tropical fruit and produces large, chunky flowers. This strain is the autoflowering version of Fat Banana, an aromatic classic that made its mark on the cannabis world with an insane scent, massive THC level, and rewarding yield.

Our breeders crossed this popular photoperiod variety — a descendant of Banana x OG Kush — with a ruderalis specimen over several generations to create a fast, impressive Indica auto. The result is a strain that's easier to grow than ever, while still delivering a great yield in record time.

Effects, Aroma, and Flavour

Fat Banana Auto inherited Indica-dominant genetics from the original strain, and much like her predecessor, she brings a body-slamming high. The effects take hold quickly, settling users into a euphoric state of deep relaxation. A high THC level fuels this potency, setting Fat Banana Auto apart from most other autoflowers on the market.

This is very much an evening strain — users may find themselves too relaxed to stay productive during the day. Cook some food, put on a good film, and settle in for a few hours of genuine couch-lock.

Fat Banana Auto's potency also gives it real medicinal value. Its calming effects are useful for reducing stress, while the physical body high can help relieve aches and pains.

On the flavour side, the original Fat Banana earned its name for good reason — bulbous buds with a fruity, sweet terpene profile. Fat Banana Auto inherits those same sugary scents, layered with banana, sweetness, and citrus fruit.
