The word for this (last) week is fan. This is the fan in my greenhouse that blows the air around and keeps the plants from overheating. Even though it isn’t that hot here it can get really hot in the greenhouse during the day – like 42 C.
I can tell it was hot this day as I had the window open. You can see I have lots of weeds in my greenhouse. They grow like crazy in the heat. And I don’t mind them as long as they stay out of my plant beds. Isn’t it cool how you can see the fan is going around.
