Our take

Purple Lemonade Auto is a sativa-leaning feminized autoflower bred from the Original Lemonade Cut crossed into the stable LSD25 Auto F5 line. It delivers a sharp lemon-sour aroma with notable sweetness and finishes the full seed-to-harvest cycle in just 9–10 weeks without any light-schedule changes. Potency runs up to 25.5% THC, making it a solid choice for intermediate growers who want strong results on a predictable timeline.

Completes the full seed-to-harvest cycle in 9–10 weeks indoors or out — no light-schedule changes needed
Indoor yields reach 1.5–1.8 oz/ft², with outdoor plants capable of producing up to 11 oz each
XL-sized plants stretch 31–51 inches tall, giving heavy harvests while still fitting most grow tents and backyard gardens

Growing notes

Purple Lemonade Auto suits indoor tents, greenhouses, outdoor gardens, and mixed-light setups equally well. Plants reach XL size — plan for up to 51 inches at harvest — so give them vertical room. The 9–10 week cycle is fixed by its autoflowering genetics, keeping timelines consistent run to run. Outdoor growers can expect wide yield variation (2–11 oz/plant) depending on sunlight hours and container size. Intermediate-level growers will get the most from it.
