Looking to start a small Highland greenhouse and have a few questions.
Starting up a 6'x8'x7' greenhouse and in my area outside temps in summer run 95-100F during the day. I will have to use a swamp cooler to keep temps low during the day. At night this summer most temps running between 80-85F at night. Will a swamp cooler allow cooling at night into the 54-60F range? Also do you need to feed swamp cooler with RO water or is tap water fine? If not will I need an AC unit/did not want to use as they lower humidity. Any suggestions would be helpful. Anyone else set up a Highland greenhouse in the hot south?
