Our take
Watermelon Z Auto is a heavily indica-leaning (60%) autoflower from Fast Buds, bred from Watermelon Z and BF Super Auto #1. It reaches up to 26% THC while delivering a layered aroma of watermelon, berry, candy, and tropical fruit. The automatic flowering cycle suits beginners who want impressive results without managing light schedules, and intermediate growers chasing serious yields.

Growing notes
Watermelon Z Auto runs a full seed-to-harvest cycle in 10 weeks and performs well indoors, outdoors, in a greenhouse, or under mixed light — making it one of the more versatile autoflowers in Fast Buds' catalog. Expect plants to finish between 47 and 55 inches tall (XXL for an auto), so give them room. Indoor yields run 1.5–1.8 oz/ft², while outdoor plants can reach 21–24 oz each under good conditions.
