Hello everyone, I just built a 17x8 greenhouse. I have an evaporative cooler that I plan to install with an exhaust fan shutter. My plan is to install one 12in exhaust fan hooked to a thermostat at the end of the greenhouse. On the other end the evaporative cooler also connected to a thermostat. This will help when the temps in my state hit 95 to 100 degrees. The problem I have is during the not so hot months including the winter when the use of the evap cooler is not needed. I thought about installing two 10in intake shutters on either side of the evap cooler, will this work? And if so can they work in conjunction with the evap cooler in the summer when it does start getting too hot or would I have to close them and just use the cooler and exhaust fan? My goal would be to have the thermostat open the exhaust fan and intake shutters and if it still gets hot have the thermostat turn on the evap cooler. Is this possible?
