In this video I show different methods that I am using to heat my newly built 16 meter square greenhouse. The main heat source being heat generated from a batch compost pile. About the greenhouse:
Some time ago I found 4 bent tubes – I put them aside for an eventual greenhouse – Since then I have been collecting things to build this green house wood (from palettes), windows, and divers bits and pieces. What i actually bought was the special uv resistant greenhouse plastic sheet and wire. This was a low cost construction.
The green house has three areas: 1- Several shelves that are made into the hill for see germination, 2- The central path, that also is used to store the water in bins, and the compost pile, 3- A planting bed. Given that the soil is rocky clay mix where I live I created this bed using the lasagna method: layers of alternate organic matter (rich in nitrogen and carbon), compost and soil.
The methods I use to keep the green house from below zero temperatures during the night include:
The compost pile:
Other uses of the heat from the compost:
You may have noticed in the video that I had a few trays of planted seed pots on top of the compost pile. This also promotes fast sprouting.
At the time of making the video (3rd week of February) the outside temperature were between -3 degrees Celsius at night to 12 degrees Celsius and the inside temperatures inside the green house ranged between 5 degrees Celsius at night and 45 degrees Celsius during the day!
