Glad this shows the black pipe idea. I have been working on this for some time. It needs to be a double loop to work well. The air heated by the black pipe should be pulling hot air from the ceiling under the grow bed and into the bottom of the pipe in front of the window. The black pipe would continue down the back of the ceiling and under the grow bed to store heat there then empty into the well. The reverse cycle with radiant cooling at night the black pipe draws air from the well where cold air is falling from the window warms it with the stored heat the cooled air is then wormed again as it rises to the ceiling. A deep well is not necessary just the air space in the 2.5 feet below the floor. Multiple loops can be installed different diameters could be used to test which is the most effective.
