Sandi, surely you jest. Though your statement was for Cheryl, you do understand what my 600+ tropical plants mean to me (mostly orchids)? These are my babies. I don't necessary pamper them but I do want them to be healthy and not be damaged by the cold. I have heard from some that I must keep my GH around 60 F and from others that say: "Poo, the orchids will survive (brief) temperatures of even 30's". What's the truth? I have no clue. Beliefs, book-reading, and what other's tell us are what the vast majority of us base our opinions/knowledge on. The thermostats that I use are accurate to 1/2 of a degree. I just want control of the temperature inside my greenhouses, at least to the best of my ability. I have a lot invested, not only in time but also hard-earned money.
Cheryl, those thermostats came from X-PLOR CUSTOM PLASTICS, INC. and the thermostats I think can from one of their subsidiaries, KKONTROLS. I think I ordered them off either Amazon or eBay. They cost something like $41.00 each plus minimal shipping. Since all my electric heaters are remotely controlled by those thermostats, I just set the heaters at their maximum (temperature) setting. The heaters will only turn on and stay on as long as the thermostat allows them to do so. My only other control is the wattage. My heaters are 750 W, 1000 W, and 1500 W (different makes of heaters). I use the wattage that I think will be necessary depending on the outside temperature.
