AN IMPROVED ENCLOSED WATER ABSORBENT SYNTHETIC PLANT GROWTH MEDIUM

摘要

The present invention is an improved water retention that includes a recyclable synthetic plant growth medium placed within a water retention system having a permeable outer layer, polymer inner layers to block evaporation and provide for the even distribution of water absorbed through the permeable outer layer, and a water impermeable bottom layer. The top and bottom layers are sealed to enclose each of the layers. Water may also be supplied to the system through drip tubes. The improvement is a synthetic plant growth medium which includes a rionwoven polymer support form for plants, at least one delivery tube to supply nutrient fluid to the plants and attaching means to attach the delivery tubes to the polymer form and a root barrier to separate the form from the evaporation and water distribution layers. The improvement also includes a water removal system in the water distribution layer. Also presented is a system to recirculate water and nutrients into and out of the improved system.
