Interesting green house design
This green house is designed with water tanks as the back wall (for thermo mass heat storage). The green house is built partly underground to control temperatures. So the house is warm in winter, cool in summer. Then they added a rocket mass heater with pipes running under the raised beds to warm the soil. warm soil is great for starting plants. The south facing plastic walls collect the sun and heat. I guess it's a insulation they are spraying on the frame in this video. I think the trench here is the path you walk in, and the raised beds are on either side of the path?
and another passive solar green house...
