Hello all. After building a really quick and cheap hoop house last fall, I've been contemplating buying or building a small greenhouse. I do have a few concerns. I can't figure out how I could possibly manage the heat without some sort of sophisticated (and therefore expensive) automated system.
Here's my problem. We have a small greenhouse here at work...one very much like the one I would want for home. But during the day the temps get WAY to high in there. Yesterday afternoon the outside temps were in the mid 60's, and the temps shot over 120 with the vent panel on top open to the widest setting (its a roughly 2 foot by 2 foot panel hinged on one side and vented open about 4 inches on the other. It's no big deal here at work because I can run down every hour or so and open and close the door and vent to regulate temp. But I can't leave plants in there over the weekend, and I certainly couldn't use this set-up at home.
At home, most days I leave before dark and don't return until 5 or 6 o'clock in the evening. There would be plenty of days where if I open it up in the morning before I leave, I could kill the plants because of the cold and yet if I leave it closed up things would bake to death in the afternoon.
So, how does one manage that?
Thanks for any ideas!
