About: Hydroponics is a method of growing plants using mineral nutrient solutions in water without soil. Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. Hydroponic produce is considered by many to have a higher nutrient content than produce grow in soil.
Storage: Refrigerate all greens in the coldest part of the refrigerator. You want to keep them moist but not wet- store in a damp cotton or mesh bag or wrapped in paper towels. The lettuce will dry up without a bag.
