YL . just funnin with ya, tho I guess it could be used to dehumidify in a pinch

I believe it that were my setup, I would cut vent holes in the top of the cabinet, cover with some readily available louvered vent covers, and mount one, possibly 2 4" fans up there below the vents blowing out. Have the fans either wired to the same timer that turns lights off and on , or really trick, have a Ranco or Johnson controller turn them off and on based on temp setpoint(trick but $, the timer option is cheap and effective)
