Grow Organic Food Easily and Inexpensively
The HAPI project has released a video demonstrating the primary components and operation of a simple hydroponic raft. The system is extremely low-tech. It uses a single light and an air pump to grow 24 plants in 8' sq. The raft takes about about $200 and 3 hours to build and will produce food for many years. Check out the video on youtube!
