Title: Cellular moist film plant culture system

Abstract: A system for growing a plant is provided in which an envelope defines a space in which the roots of the plant grow. Sheets of porous, flexible material which carry a number of nutrient packs are supported within the envelope. The sheets are partially submerged in a water reservoir and are constantly moistened by capillary action. The roots of the plant are physically supported by the sheets of flexible, absorbent material, and receive nutrients therefrom by absorbing nutrients which dissolve from the nutrient packs and pass through the moist film and into the root structure at a rate which increases with the rate of consumption of the nutrients by the plant.
