l started to make plans for a greenhouse l plan to build in the late summer, to be able to feed my family fresh fruits and veggies year round.
Makeing a greanhouse isnt hard if you have lots of money and resources, but a DIY cheap efficiant HEATED greenhouse culd be a nother thing. And this is what l plan to do.
Ok here is the big idea
This will be half (north side) dug in to ground (positioned on a hill).
The shell will be made with 2 layrs of bubblewrap foil (insulation) and thick UV resistant foil on top, to protect it from the elements.
The winegrape on the top partialy shades half of the greenhouse in the summer, thus preventing overheating (ventilation will still be nessesery) while provideing unlimited sunlight in winter, when the leafes fall down.
There will be 2 compartments in. A semy warm about 10-15C (lettuce, cabbage, kale, califlower, carrots...) and a warm 20 C part (tomatoes, zukinnis, paprika...)
The whole sistem will be about 3mx6m 2m high, not too big, shuld be enough for a few salads and stews in the winter.
l wrote down the Farming part, now for the woodgas part!
l plan to heat the greenhouse with wood. Exactly how, l wanted to discuss with you guys.
Features l want the sistem to have are:
-being able to run for a long time unnatended
-produce a constant output of about 2kw (just a WAG)
-be out of the way
-burn cheap DIY fuel
-work without electricity (this one isnt so important)
this is a top wiew.
l am leaning towards JO"s woodgas boiler style sistem. A woodgas burner with insulated hot water reseroar, both out of the way under the path between the greenhouse compartments.
lf anyone has any suggestion or ideas, experiances perhaps, plese, do chim in!
