Nexus Zephr, 31' X 37', 10' columns, 18' peak, 2' X 37' roof vent rack and pinion, 4' x 37' south facing (prevailing winds) wall vent drop down guillotine type, iLink controller, Lock 1 HP motors, 6 cooling set points (vents, equipment), 2 heating set points, Melnor fan forced propane heater. Best of all is the Palram SolarSoft 90 polycarb. on the walls, clear on the north roof, SolarSoft85 on the south roof. Rootbuilder bottomless pots. 305 gal. rainwater collection system with pump. First avocado cost me $30,000 but at least I don't have to move my plants in and out and can grow just about anything.
6 mos. of research went into this. Tropicals need plenty of light. Beware of twin wall, it shades a bit compared to corrugated.
Misters only work, or better put, you'll work far less and there's no white on your leaves...... if your water source is very soft. I'm eventually going to go with a high pressure pump, 1,000 psi, driving flash vapor type nozzles with rings around the swamp coolers and hang some in the rafters. Due to hard well water will have to either install a water softener before a R/O system with tank, filters, etc. or put in a huge rainwater tank.
Clear north roof.
I now have hundreds of pollinators (and a finch) that come and go thru the open vents on flowering mango, avocado, citrus, pitaya, volunteer tomatoes, etc. For some strange reason flies choose my Gwen avocado. Have many varieties of bees, flies, moths, butterflies. You need to provide ample open areas for pollinators to come and go. They get confused when there's no UV light cause of the covering and won't find their way out.
Man cave!
