Building the glasshouse

A big project, but one that should deliver very significant benefits. The primary objective is to extend the growing season at both ends to allow for easier more predictable results for things like capsicums, cucumbers and other frost sensitive plants.

The main feature is a north facing stone wall sealed behind a skin of rigid plastic. This acts a simple trombe wall. With concrete vents buried beneath each of the four garden beds. A passive solar cycle will drag slowly warming air through the vents, imparting some of that heat to the soil.

A 'key hole' type garden bed layout allows for easy access to reach directly into the waist high beds.

Stage 5 - Plastic skin in place, sliding door, five bottom hinging windows. Water on, transplanted peppers, tomato and basil in a rich 'lasagne' of rotten wood, decomposing leaves, seaweed, chook house cleanings and pig manure. Mmmmmm.
