just get a cheap irrigation timer at one of the home stores that can run 2 zones and three cycles on each zone and set the misters to run 6 times a day for 2-3 minutes during the hot parts of the day.
Mine come on the first time at 11 am for 2 minutes, then 12 for 2 minutes, then 1pm for 2 minutes, 2pm for 2 minutes, and 3 pm for 2 minutes. If it gets hotter, then put them on for 3-4 minutes instead. It will dampen down the greenhouse and keep it cooler, and increase the humidity. It sounds like the humidity isn't going to be a problem for you there.
Also it sounds like your shadecloth is pretty thin, if it's 110 outside, you could probably use up to 50%. We're running 30% shadecloth all the time on our greenhouse with no adverse effects. We don't take it off during certain hours or anything like that. They grow foliage plants in Florida under 50-70% all the time.
We have rusty well water with lots of iron and calcium. We get a little buildup sometimes, but it doesn't adversely affect the plant that we can see.
