That only applies if you comparing both for heating only. A gas heated green house is still going to cost more than a heated room that you are already paying to heat whether you use it or not. Additionally, I have yet to see a fully insulated green house, and thus you are going to lose heat just as fast as you make it. in other words the gas is going to be burning your $$$ constantly. I was talking to another member here whose mother has a green house she uses all year long . Her costs last year if I remember correctly were$ 4,000.00. Conversely, It dont pay to be burning HIDs or growing indoors during the summer either if you dont need to.willard3 said:Electricity costs 2- 3 times as much per btu as oil or gas.
20.00 greenhouse?? Do tell.spicy_echo said:I grew mine in my garage last year using a cheap $20 greenhouse and about 10 100w CFL bulbs on a surge protector strip. It gets down in the 10's and 20's here in the winter often times. Granted I'm sure they didn't grow as fast as they would in a warmer climate (in the house) but if that's all you have to work with then it's very doable. I was ready to plant come late April/early May.
