Demolision site cuts costs galore, and superb seasoned wood to boot. A good callapable basket, less than a £1 for the hingis. 1 inch frame, and some clothe. Dried old house bricks great for grit. Spring water / Mole hills free for minerals etc. Stinging nettles and Thistles for Iron and good blood and air circulation. Guess it depends on how much you wanna pay and or work / time. The real bit is that many start of buying the 'Brands. Then the Supermarkets... then the countryside of nature. But a good frame set up and Plastic Cladding is superb and very cost effective.
