Washing & Curing Engineering Notes for Fatso
Because Fatso (GMO x Legend OG) expresses a dominant Beta-Caryophyllene, Myrcene, Humulene terpene profile and collects heavily in the 73u - 149u sieve bags, maintain wash water at 32F-34F with minimal shear vortex during the first two 6-minute washes. Lyophilize at a 40F-45F shelf temperature limit, press at 154F - 164F, and whip after 72 hours at 64F to lock in a glossy Gassy Greasy Cold-Cure Badder consistency.
