Old Prospector liked a post in a topic: Maintaining Water and Air Temperature During Winter
Jack posted a topic in EQUIPMENTI live in northeast Tennessee were soon the temperature will start dropping. I'm running DWC in a greenhouse and have been thinking about options to maintain optimum air and water temperatures. I'm running 110 liter air pump with 12 air stones distributed throughout a 720 gal channels. Today, I thought about introducing warm air (e.g., at 100F) into the air pump inlet and wondered if the warm bubbles introduced to the water might provide a means for temperature control to both the water (roots) and air (leaves). To facilitate holding the heat in the air, I can add catipiller tunnels to the DWC channels overlaid with clear plastic. Any thoughts as to whether this has been tried, might work, and any thoughts wrt design? An option I thought worth considering for heating the air would be to require the air entering the air pump to pass through a heated pipe.
