Help! Greenhouse too hot
Our school greenhouse was built without proper ventilation and with our early spring this year, temps are hitting 110 F and higher. I was able to move some of the plants out into a light filled hallway for the weekend, but those pesky students return on Monday and I'll have to move them back to the greenhouse.
It is a permanent glass structure built onto the side of a classroom on the second floor of our school. It's wonderful until late April/early May. There are blinds that I can close on the wall windows, but the blinds on the roof windows won't close because of gravity (some genius must have been in charge of the design).
I've been trying to think of ideas and done a little research. I'm thinking shade cloth attached to the roof blinds with clothes pins? Some sort of water cooling system?
Anyone have any other brilliant ideas? Cost is, of course, a factor.
