The walipini, or underground greenhouse as it is often known, can be easy to build and extends the food growing season.
By using solar heat, windows facing the sun, and thick walls, growers in temperate and cool climates can grow into winter.
A great solution for our ever changing climate and for those making a living from growing vegetables.
Below is Shaun's own walipini.
