We’ve started having highs in the upper 70s lately (after having nighttime lows of 28° F and ice on the horse water tank next more at the beginning of the week 😫). It doesn’t take long for the temperature in the greenhouse to get pretty warm (105° yesterday!), so the exhaust fan has been running by mid-morning. Just because I was bored and had nothing else pressing at the moment, I pulled out the dismantled “swamp cooler” equipment, switched out the burned-out box fan with a new one, and had everything back up and running before long. Turned it on and it dropped the temperature from 89.7° to 84.3 in under 15 minutes.

Ah, the challenges of greenhouse ownership!
