A sign of spring in New York

Sharon, when summer comes, it will get actually too hot in the greenhouse. Do have 3 thermometers in it. One in normal shade, One in direct sun, and another inbetween.

At 95 in the shade plants are hurting, but look at the sun thermometer. It may show 120 or higher!

Most plants are hurting at 95 shade or not.

In summer, ventilation becomes important, fans, doors, shade, water. Have things easy to move out and in.
 
Sharon,
As usual Marshall is right on the money with his advice, and especially regarding summer. On hot sunny days I cover the greenhouse with a 45% shade cloth. In addition, I open the vents and door and run a ventilating fan. If the temperature is approaching the mid nineties I spray the floor with water so the evaporation will help cool the greenhouse. There is a little more to it than just putting plants in there. Good luck.
