Master Bruce SOS is a 50/50 hybrid autoflower created by Secret Owl Society, blending Bruce Banner #3 Auto F3 with a Master Kush-leaning Blue Power Auto F3 phenotype.

This frosty, flavor-rich cultivar brings together old-school kush depth and modern autoflower performance—resulting in a compact powerhouse that hits hard, smells loud, and finishes fast.

Typically finishing in 70–80 days from sprout, Master Bruce puts out dense, trichome-covered buds that carry deep notes of hash, sandalwood, berry, and gas.

With high resin output and a calming-yet-uplifting effect, she shines in both flower and hash form.

Expect a well-balanced, full-spectrum experience that’s functional by day and relaxing by night.
