Our take

Purple Punch Auto is a heavily indica-leaning (85%) feminized autoflower with a distinctly dessert-forward profile — think blueberry muffins and ripe cherry with a hint of spice. At up to 24% THC and a 9-week seed-to-harvest cycle, it rewards both first-time growers and experienced hands who want a reliable, fast-finishing plant without managing light schedules.

Completes the full seed-to-harvest cycle in just 9 weeks — no light-schedule changes required
Indoor yields reach 1.5–2 oz/ft², with outdoor plants capable of producing up to 7 oz each
Grows to 35–59 inches, making it one of the larger autoflower options for growers with vertical space

Growing notes

Rated XXL for an autoflower, Purple Punch Auto can stretch to nearly 5 feet, so plan your vertical space accordingly — especially indoors. It performs well in a range of settings: indoor tents, greenhouses, mixed-light setups, and outdoor gardens. The 9-week total cycle keeps things straightforward for beginners, while the yield potential gives more experienced growers something to work toward.
