Chinampa

We can try to build a chinampa inside our greenhouse.. (water/land mosaik). They are ideally 6m wide and 1.5m deep – which is ideal for a greenhouse. Half meter thick clay should seal the dam/chinampa. Put a greenhouse over one end to heat it and a net house over the other to cool it and your water will move through a thermosyphon that moves your water from hot to cold automatically.
