Abstract: An improved system for growing plants is provided which includes an envelope having a closable seam along at least one edge and having sheets of porous flexible material which carry a number of dry nutrient packs supported within the envelope. Plants may be inserted at intervals along the open seam and the seam partly closed by clamping means around the stems of each of the plants. In one embodiment of the invention a vertical configuration is employed while in other embodiments, a horizontal configuration is employed.

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.
