I just bought the Dreamhouse Greenhouse from www.patiostore.com/greenhouse/FlowerDream.html and would like to know what size electrical heater do I need for that greenhouse? I want to grow vegetables in it.

Here is a heater calculator. You need to know the minimum temp, the temp you want to keep the GH, and the surface area of the GH. My guess is that you would use the 4 mil or 6 mil poly heat loss value.

4000 BTU should be more than enough

Thanks everyone, I'm a new gardener and thought since I live in the coldest part of Florida (zone 8 B), close to Pensacola I could start a little earlier with a portable greenhouse.
