What is the Mittleider Method?

The Mittleider Method combines the best features of soil-based gardening and hydroponic gardening, but without hydroponic expense! It's a complete, easy-to-follow plan that eliminates guesswork and ensures success anywhere: an apartment patio, a city yard, a country lot, or a farm.
The method is based on maximum utilization of space, time, and resources. Crops are large because plants are close together, nourished by supplemental feedings of natural mineral nutrients (as in hydroponics), but with no special equipment.
Also, unlike hydroponics, the Mittleider Method gives plants access to the natural soil for nutrients as yet unknown or that, while not essential to plant growth, are useful in human nutrition. You can use the Mittleider Method by raising crops in either soil-beds or grow-boxes.   source
