Outdoor grow vats

[CrayolaViolence]

I put this on the coral propagation forum and got no bites, so I figured I would try here.

"I'm curious as to what methods are utilized to keep water and corals warm by people in colder climates for outdoor green houses. I'm specially interested in greenhouses that don't use electricity but harness the power of the sun. Is there even a logistical way to keep the water warm enough to maintain corals and or macro algae without having to knit them all little wool coats?

Thanks in advance---and yes, I'm kicking around the idea of an outdoor greenhouse for macro algae. Just need to figure out a way to do it and not use electricity and run up the light bill."

You could watch some of Tidal Gardens videos on youtube. He runs a greenhouse coral operation in Ohio. Lots of useful information and always great videos. Summer is very hot and winter is very cold. He installed a heated water system in the concrete floor to heat the greenhouse in the winter. I don't think there is a solution without electricity, to be honest.
