Pound Cake Auto is a true dessert strain from Fast Buds. The breeders crossed two of their established F5 lines, Strawberry Banana Auto and White Widow Auto, and stabilized the result as an F3 feminized polyhybrid autoflower with a 60% Sativa / 40% Indica balance.
The headline numbers: up to 28% THC and 450-600 g/m² (1.5-2 oz/ft²) indoors, in a plant that goes from seed to harvest in about 10 weeks. Outdoors and in greenhouses, single plants yield 60-300 g (3-11 oz) depending on season and pot size.
She is an autoflower, so there is no need to flip to 12/12. Keep her on 18/6 or 20/4 throughout. Fast Buds rates her as XXL: plants reach 90-150 cm (35-59 inches), building one big main cola and strong side branches. Even so, she stays easy to handle and asks for very little maintenance.
Late in bloom, the sugar leaves often fade into orange, pink and purple tones, giving the buds plenty of bag appeal.
Flavor and Effect
The aroma lands somewhere between a berry cupcake and a bakery counter: sweet mixed berries, hazelnut and vanilla cream with a smooth, nutty finish. The cream-and-fruit profile runs through the whole cure and stays rich in the jar.
Most growers describe the high as happy and relaxed, with a social, talkative start that slowly settles into a calm body feel. It is well suited to get-togethers, movie nights or unwinding at the end of the day without feeling knocked out.
Growing Tips
Pound Cake Auto rewards simple care. Give her a roomy container, steady light and a balanced feeding program, then add stakes or a trellis during the last few weeks when the main cola and side branches load up with weight.
Outdoors and in greenhouses she adapts well, and her wide yield range of 60-300 g (3-11 oz) per plant mostly comes down to container size and hours of direct sun. A large pot and a sunny spot push her toward the top of that range.
Light low-stress training early in veg can widen the canopy and improve light penetration to the side branches without slowing her down.
