Ive been trying to figure out how to heat a small greenhouse or coldframe without electricity. Looking onto solar, water heater pumps run on 12v batteries. Still havent found a good solution. But LOOK at this pop can heater:
1/2″ Insulation. Popcans. Black Spray Paint. Glass & duct tape.
There are quite a few people making these pop can heaters on youtube. Now to figure out how to structure it (size, placement) to heat a small greenhouse or cold frame.
Pop Can Heater gets up to 170 Degrees
