Hydroponic apparatus using elliptical conduit

摘要

Hydroponic apparatus comprising an elongate hollow conduit (2) of substantially elliptical cross section having inlet means (8) for introducing a nutrient solution into said conduit, outlet means (10) for allowing nutrient solution to exit said conduit and at least one opening (4) formed in said conduit through which a seedling (18) may extend, at least some of the seedling's roots being retained within the conduit. The elliptical shape of the conduit provides enhanced plant growth by allowing better lateral growth of the root ball and increased contact of the root ball with the nutrient.
