From Robert Butt, the author... "Hydroponics is soil-less cultivation with a recycling water/nutrient system. It allows us to grow plants at an accelerated rate since we can control the elements which all plants require. Not only is it visually amazing it's a lot of fun And, as the home farmer, you get to reap what you have sown - sans soil - with flavor greatly enhanced."
