Sundae Frost Auto: frost, colour and a 70–75 day cycle
Sundae Frost Auto is one of Fast Buds’ latest autoflower releases, made for growers who want fast results without giving up potency. It comes from a cross between Frostbanger Auto F4, one of the bank’s most resinous autos, and Sundae Thumper. The result is a balanced F1 hybrid, 50% sativa and 50% indica, reaching up to 30% THC according to Fast Buds.
An easy-to-manage plant with two colourful phenotypes
Fast Buds describes two phenotypes. Both produce green buds with purple hues, and one also develops dark, almost black leaves that look stunning in late flowering. Plants stay between 60 and 100 cm, so they fit easily in a grow tent, on a balcony or on a terrace. Indoors they yield 450–600 g/m², and outdoors 80–250 g per plant. It takes 70–75 days from germination to harvest.
Aroma, flavour and effect
Both phenotypes share the same profile: sweet, spicy and very fresh, over a fruity base. A dessert-like profile that recalls its Sundae parent.
According to growers, its effect kicks off with a happy, euphoric rush that, over the minutes, turns into body-centred relaxation without clouding the mind. With up to 30% THC, it’s best enjoyed in moderation.

Growing tips
Like all autoflowers, Sundae Frost Auto switches to flowering on its own, with no change in light schedule. Sow it straight into its final pot to avoid transplant stress, give it 18–20 hours of light indoors and start feeding at gentle doses. For week-by-week doses, see our Grotek feed chart for autoflowers.
