We are rather fond of this plant. The non-psychoactive Cannabis species. Sustainable. Food, clothing, ropes, building – the list is long. Some history and uses of industrial hemp here, and more about the nutritional value of the seeds here – vegans take note.
Fortunately the plant has a champion in Tony Budden (Nominative determinism anyone?) of Hemporium SA. The site has an on-line shop and plenty of excellent information. Inhabitat interviewed him, and here is more. We also enjoyed this site. Find plenty of video goodness here about building with hemp.
