Odd idea struck me. People now heating their homes by using solar energy to heat water and then run the water threw radiator like networks under their floor. Of course you would have to regulate the heck out the temperature, but I wonder about doing the same to heat the water in a hydroponic / aquaponic system. Idea being the radiant heat might be able to provide enough warmth to heat the area sufficient to keep the foliage happy.
Thoughts?
