Even though I haven't use the misting fan, one problem I can forsee will happen... too wet because of all the mist!!

I always feel evap cooling is the next best thing to cool down a growing area during day time (cost wise if compared to A/C) To get the desired night time cooling to simulate a intermediate condition, I still think A/C unit will be needed. The good thing about evap cooling is that it saturate the air with high humidity without actually getting anything wet... perhaps just the evap cooling pad. If I were to setup some sort of cool house, I will be leaning towards evap cooling (day and night time ) + A/C unit (night time only).
