Hi Willow,

From Wikipedia... "John Zerzan (born 1943) is an American anarchist and primitivist philosopher and author. His works criticize agricultural civilization as inherently oppressive, and advocate drawing upon the ways of life of prehistoric humans as an inspiration for what a free society should look like. Some of his criticism has extended as far as challenging domestication, language, symbolic thought (such as mathematics and art) and the concept of time. His five major books are Elements of Refusal (1988), Future Primitive and Other Essays (1994), Running on Emptiness (2002), Against Civilization: Readings and Reflections (2005) and Twilight of the Machines (2008)."

Video 13. How to Make an Inexpensive Miniature Greenhouse [3 mins]



[START] PVC drinking water pipe (he uses white) 0.5 inch internal diameter, 10 feet length [not sure of the viability of this, in the UK we are on the metric system and may use different plastics, eg HDPE. Our pipe would be 15mm. Need to check this out] at a DIY store]. Bend them into the soil to make hoops. He does 3 hoops about 2 to 3 feet apart. Maybe use a stake if soil hard. Just use it as a cover over a flower bed [what he is making looks more like a large "cold frame", see http://images.google.com/images?q=cold%20frame]

[2 mins] Use a simple plastic drop cloth (looks like polythene sheet but is less transparent). Roll some pipe into the plastic each side until it's tight and pin them down with garden staples - around 15 to 18 inches apart. As they rust the grip will improve.

[3 mins] You can use the same method on the ends - can use clip ties on one end for access [just let it hang down, and you can pin the rolled material to the hoop shape as a tent door is tied back]. You can leave the south end open in good weather so it doesn't overheat in the daytime and creates a micro-climate, it also keeps the frost from killing the tender plants at night, only a hard freeze will penetrate.

Very cheap but works well. [END]
