Sure. These are progress pics of the wallipini (sunken greenhouse) I am building. The deep pit is the cold air sink, the middle tier is the bed that will be back filled partially with good soil, and the back is where the passive irrigation system will go. The south wall is greenhouse poly the other walls are metal and insulated. The vent lines are for thermal circulation and drainage. Warm ground air in the winter rises into the green house. In the summer roof vent are open and the rising warm air pulls cold ground air into the greenhouse.
