ABSTRACT:
A greenhouse structure for growing plants using nutrient feed solution. The structure comprises a plurality of elongated greenhouse production areas. Each area has a shell and a base enclosing a predetermined space within which plants are grown. The areas radially extend outwardly from a central supply area in which nutrient feed solution is supplied to the production areas is kept. The base of each of the production areas are sloped upwardly in the direction away from the central supply area so that excess nutrient feed solution passing to the production areas will return by gravity flow to the central supply area. The structure further provides pump and conduit means to supply nutrient feed solution from the central supply area to the production areas. The conduit means are sloped to return by gravity flow excess nutrient from the production areas to the central supply area. The structure according to the present invention provides for easy maintenance increased hygiene (through drainage of any non-processed water from the production zone on a continuous basis) and increased security (through collection of any nutrient solution or water in the system if required and quick detection and repair of any leaks).
