Our take
Guava Auto is a balanced 50/50 sativa-indica autoflower bred by Fast Buds that delivers a strong tropical punch — up to 28% THC — in just 8 to 9 weeks from seed, no light-schedule changes needed. The aroma is ripe guava with a clean sweetness throughout. A good fit for intermediate growers and patient beginners who want serious results without a complicated setup.

Growing notes
Guava Auto suits indoor tents, outdoor beds, greenhouses, and mixed-light setups equally well. Plants reach XL size (up to 47 inches), so allow vertical space or plan low-stress training early. Expect 1.5–1.8 oz/ft² indoors; outdoor plants vary widely — 2 to 7 oz depending on conditions and pot size. Because it's an autoflower, it flowers on its own schedule without any light-cycle adjustment.
