I put a remote temperature sensor in the wheeled greenhouse that I built, and can monitor the temperature from my house. Before any plants were put in this year the door was kept shut and on one sunny cold day it reached 110 F (43 C) inside, so I know that I can't leave the door shut unless absolutely sure that it will be an overcast day. It's better to leave them some ventilation than take a chance on burning the plants up. An automatic temperature activated door opener would be nice, if it worked.
