While I was kvetching yesterday about the 100°F temps in the shadehouse, DH surprised me with a "why don't we put in an evaporative misting system?" After doing a little looking around, I think I need a pump with at least 1000psi, because I want the water to instantly evaporate and not add any liquid water to the plants. (I've been attempting to cool with one-minute intervals of running my irrigation, but I'm beginning to see weakening in my new growths from too much water.) Anybody have any vendor recommendations? I don't want a misting system that relies on fans for distribution; rather, we will install nozzles all along the ceiling. At least that's the plan. I'd also like the pump to be thermostat activated, so any advice on that would be appreciated, too. (Along with a vendor recommendation for the thermostat.) Also, it seems to me that a misting system might help maintain warmth in the Looking Glass on 50° winter nights. We don't get many, but a few. Is this the case? My shadehouse is 24'x36' / 8640 cubic feet... Thanks!
