Climate control in GH with fogging, swamp coolers and ventilation

[nutgirl]

My summer conditions are hot and dry. My greenhouse is 8x12.
I have a wall ventilation fan and a swamp cooler on thermostats and a mister on a timer.

The thermostats are set so the fan comes on first and if it gets too hot then the cooler kicks in.
I use the misters in the afternoon when the dry heat is greatest but not for too long.
Ray is right about the cooler needing to be outside. I keep the door of the GH open all the time in summer.

It doesn't need to be a jungle in there. I've seen a noticeable improvement in my plants with just the humidity the cooler provides.

Thanks, especially from all the California responders. I have some aerial, most of the potted stuff is in SH-LECA, or very dry bark-Lava also to avoid them getting overwatered. I found the Intermediate and cool growers do need finer more retentive mix, and have been slow to adopt to SH culture for me (sorry Ray).
I decided to run the Swamp cooler (placed on outside) on a thermostat the cool air will pump near the large circulation fan. I will make a small fogger (3 head) in a 5G bucket with small fan and set that on a Humidistat. The ventilation windows already work well with the automatic openers so I should be good.
