My plan is to put 2 chop and flip and a 4' by 12' grow bed system in a greenhouse. The greenhouse will get a barrel stove. I'm planning to wrap the barrel stove with copper tube run a continuous loop (garden hose 12v pump) into a black painted IBC tote. Heat the tote full of water and it should help provide heat and humidity to the greenhouse in winter. Also I can submerge a copper coil tube in the black IBC and pipe it anywhere in need warm water. Definitely putting a coil of heated water around my fish tanks. I'm not trying to keep a poly tunnel at 80°f. Just trying to keep it above plant killing temps.
I'm still in the drawing stages. Given my history as a carpenter and blacksmith, and low voltage tech I'm confident with God's help I can make it work.
Also it may cost me $600.00 in copper tube alone. So baby steps!
