Hello!
I am new here. I just finished building my Hoop greenhouse with 12mil woven covering. It's 16ft x 20ft. The end walls will be more insulated.
I am trying to figure out how to best heat it this upcoming winter. As of right now I only have 110V/120V available to use. There are some Heaters out there but not sure what I could do to make that work and not sure how many I would need.
Maybe next year I can get a Gas line or 240V installed but not for this winter.
Does anyone have any Ideas/suggestions.I live in KY and last winter we had two or so days where it got down to 0F but other than that it stayed around 20F on the low end for a month and then low 30s or warmer.

Thanks
