Can we talk greenhouses? We bought a small lightweight greenhouse to try to keep our pool plants alive over the winter, but they basically all froze to death anyway. We are in North Carolina. What kind of heater should we have put in?
I’m passing you on to a few of the ‘greenhouse’ experts here. My greenhouse is unheated, so I don’t know what would be needed.
Sorry for your loss, though. :(

I have a one of those tiny cheap (i.e., Chinese) “greenhouses”; its footprint is about 2’ x 3’. I’ve had very good luck using a string of Christmas lights to keep it warm overnight. The bulbs have to be the traditional incandescent type; the modern LCDs or whatever they are don’t give off any heat. It’s very festive too!
I'm in zone 6b. 8'x12' greenhouse.
I use a cheap 1500w electric radiant heater. It doesn't keep the greenhouse "warm", but it's enough to take the edge off of bitter nights.
We had fresh lettuce and spinach last winter in spite of some extended periods of very cold weather.
That said, if you want to keep your greenhouse "warm" you'll want to install some sort of gas heat like you see in larger commercial greenhouses.
yldstrk, If you are overwintering pool plants, like water lilies, are you putting them in something like a tub or child’s pool in your greenhouse? Do you have a photo?
