Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
77 words
An automated controlled environment apparatus for continuous production of plant life comprising: A. an elongated horizontally disposed conduit, B. a flotation pool of water of a predetermined depth in the lower portion of the conduit, C. buoyant plant supporting elements floating on the surface of the pool, D. and air circulating means within the conduit adapted to produce air movement longitudinally of the conduit over the pool surface to move the plant-supporting elements along the pool surface.
Claim 2
Dependent Claim
77 words
