I've been using my Starter Misting System v4.0 since April 2016 in my little 6 ft by 8 ft greenhouse to help keep the temperature below 90 deg F. It was easy to set up and adjust. Actually it helps to humidify and mist my mounted orchids as well as control high temps. Just be sure to have plenty of air circulation. The pump is a beast, it is really reliable. I use RO water to help keep the mist nozzles free from clogging. A great investment for my orchid greenhouse!
