Our take
Sundae Frost Auto is a 50/50 indica-sativa F1 hybrid from Fast Buds, bred by crossing Frostbanger Auto F4 with Sundae Thumper. It stands out for reaching up to 30% THC in just 7–8 weeks from seed—no light-schedule changes needed. The aroma runs sweet and fruity with a spicy edge. A solid pick for intermediate growers ready to push potency.

Growing notes
Sundae Frost Auto suits indoor, outdoor, greenhouse, and mixed-light setups. Plants reach 23–39 inches at harvest (size class L), so allow enough vertical space indoors. The 7–8 week seed-to-harvest cycle is fixed by the autoflowering trait. Outdoor growers can expect 3–9 oz per plant depending on conditions. Best suited to growers with a few grows under their belt who want to maximize yield and potency.
