Fat Banana is the result of a focused selective breeding project at Royal Queen Seeds, aimed at a strain with traits rarely seen together. The parentage is Banana crossed with OG Kush, a heritage with real power behind it, and the outcome is a 70% indica feminized photoperiod that collectors, connoisseurs and growers all find hard to resist.
Potency is a defining feature. Fat Banana can reach up to 25% THC in skilled hands, and the buds come wrapped in a sweet, fruity banana aroma that is instantly recognizable once you have smelled it.
Indoors, plants grow to 3 to 5 feet (90–150 cm) and yield 12 to 14 oz/m² (340–395 g/m²) after 55 to 65 days of bloom. Outdoors, Fat Banana can reach 170–200 cm (5.6–6.6 feet) and produce 16 to 18 oz/plant (455–510 g/plant), ready in late September.
Effects and Flavor: The Kush Nobody Saw Coming
The opening act is gentle. A mild, euphoric lift and a mouthwatering sweet flavor can lull you into reaching for another hit. Don’t be fooled: this strain is potent. A strong physical stone creeps up and takes hold, followed by a wave of deep calm that settles into every muscle.
Expect the munchies and plan accordingly. Fat Banana is a trip to flavor country that tends to begin and end on the couch, which makes it an evening strain through and through.
The taste is sweet with bright hints of citrus, while the aroma leans heavily on ripe banana, backed by earthy depth, a touch of pepper and a skunky Kush undertone. It is a delight for the nose and a standout in any jar collection.
Growing Fat Banana Seeds
Despite being indica-dominant, Fat Banana behaves like something of a stretch indica. Left untrained, she tends to push up one enormous main cola. Topping early, or LST and a SCROG net, spreads that energy across several tops for a more even canopy and better light penetration.
Bloom runs about 8 to 9.5 weeks indoors. Outdoors, in warm, sunny conditions, Fat Banana can turn into a monster bush that will likely need stakes or a trellis to carry the weight of her chunky nuggets. Royal Queen Seeds rates her for regions with short summers, with harvest arriving in late September.
