Simple hydroponics
The Asian Vegetable Research and Development Center (AVRDC) has developed a simple hydroponic system for growing vegetables, using old clothes and plastic cups as a basis. Old plastic cups are perforated and filled with an absorbent medium such as rice hulls, or even cut-up old clothes. The seeds are sown into this material and the cups placed into a nutrient solution which can be contained in old crates lined with plastic sheeting. The bottom of the cup is covered to a depth of about two centimeters. Plant roots extend down into the solution and take up nutriments. Other roots develop above the nutrient level and absorb oxygen. The nutrient solution in made up to a recipe developed by AVRDC. Trials have shown that the materials and solution can grow several crops before they have to be discarded include oninos, potatoes and a wide range of leaf vegetables. This technique would be useful for people living in towns. AVRDC PO Box 205, Taipei 10099 TAIWAN.
