Our take

Big Bang Auto is an 80% indica-leaning autoflower built on a classic four-way cross — Skunk, Northern Light, El Niño, and Ruderalis. It reaches up to 19% THC and delivers a layered scent of sweet fruit with a spicy edge. Because it flowers automatically without any light-schedule changes, it's a practical choice for first-time growers and experienced hands who simply want a dependable, fast-finishing plant.

Completes the full seed-to-harvest cycle in just 6–7 weeks indoors
Indoor yields reach 2.5–3 oz per square foot — strong output for an autoflower
Grows in virtually any setup: indoor tent, outdoor garden, greenhouse, or mixed-light space

Growing notes

Big Bang Auto suits a wide range of environments and is forgiving enough for newer growers. Expect plants to finish between 23 and 40 inches tall — manageable in a standard grow tent. Indoors, plan for 2.5–3 oz per square foot; outdoors, each plant typically yields 1.4–1.8 oz. No light-schedule change is ever needed. The 6–7 week cycle makes back-to-back runs entirely realistic.
