In the realm of innovative growing techniques aeroponic growing is among the more obscure. It challenges just about everything the average person knows about farming by cultivating crops not in soil or even water (as in hydroponics) but in open air. To understand aeroponics, imagine a plant plucked from the ground, roots and all, and held in place so that the roots remain suspended.  An artificial light source supplies the energy needed for photosynthesis and a nutrient-infused mist is applied at periodic intervals. Direct, efficient uptake reduces water usage by an estimated 90 to 98 percent compared to traditionally grown crops, fertilizer by 60 percent. A sterile growing environment and the plant's healthy immune system eliminates the need for pesticides altogether. When not absorbing water and minerals, the roots receive a direct, abundant supply of oxygen, and the delicate seedling grows faster and more robustly than its soil-bound counterparts. Soon a crop is ready for harvesting.
