Hydroponics is really a technique of growing plants without soil in nutrient solutions. Dozens of various nutrient answer compositions have been suggested over the past years, but most of them resemble one another fairly closely. The guidelines for nutrient solutions are that they contain nutrients in amounts which are typically proportional to plant tissue composition and in a total remedy concentration that doesn’t damage the plant. (Oh, and by the way, the nutrient solutions do not resemble your typical soil solutions.)
