I have a greenhouse similar to (perhaps exactly the same as) the one pictured. What sort of temperature can I expect this thing to hold over the outside air temp both through the day and night time retention?
My ideas already for heat retention include:
I can use southern exposure.
Next to my brick house.
I will build a brick platform for it to rest on.
I have thought of placing approx. 6 little Gerber 2oz. food jars on each shelf, which will contain water. Perhaps one or two 2 liter bottles of water on the bottom shelf.
I'm in zone 7, NC. and would like to get an idea of what to expect from this thing through the winter here.
If all else fails I suppose I could run an extension cord to a ceramic heat bulb placed in the unit, but I'd like to avoid the need for electricity if possible. Ideally I'd like to have nighttime drops no lower than 45F.
