Turtle, how are you running your AC in your cab? Is it mounted into it? Do window air conditioners need to be mounted intbetween to areas (for instance the outside and the room its cooling) to work, or can they just run and cool air sitting in a room. Ive been brainstorming AC's for cabs and I was thinking if the cab was big enough, one of those window AC's could just be installed into the bottom back corner? Would this negatively affect the air for the plants? and would this be considered a good air intake? Peace
