We are moving into the heat of summer, and it is necessary to install some shade cloth on the greenhouse to control the heat inside. On even a mild day in the mid-70's, the inside of the greenhouse was heating up to near 100ºF. I added a green 60% shade cloth over the top of the greenhouse to shade both sides as well as the top. As soon as the shade cloth was installed the temperature inside dropped by 15 degrees.
For those interested, I ordered the 60% shade cloth from ACF Greenhouses, which is the same company I ordered the exhaust fan and intake shutter from. I'll post a link below to their site below. They are not sponsoring this site, and I was not compensated for mentioning them, they just offered the best prices, and good service.
