Hello to all. Been a member and been reading for a while but never posted anything. Sorry if this question has been answered before but I was unable to find what I needed to know. I might be buying a 16'x100' greenhouse and would like to run year round. I want to grow vegetables, duckweed, and 2 to 4 IBC aquaponics. Now heating is my issue. Would double plastic the green house and try the black barrels with water in them, on Northside to heat up during the day. Also wanted to build the RMH for heat. I live in central Ohio so weather is all over the place at times. Now for the question, with the RMH would like to have a number I would need, placement and running the pipe (size pipe as well) to heat. In my mind I thought I would run it underground but that is a long stretch. Any thoughts and help would be great.
Thanks in advance,
