Most are getting about 6-8 ounces per 66qt mono tub. 2 zips is pretty weak broI did cakes like twice and never again. it looks cool and all just don't get much. I use turkey trays now, in a 66qt tub with either a pond fogger or water at the bottom with a fish tank heater and bubbler. Works every time and I get 2 ounces a tray DRY!!
