Problems solved by technology

However, additional treatment of the plants increases production costs
Another disadvantage of round hydroponic tubes is that they are too "deep" for some plants, such as lettuce and pastures, which only have very shallow root balls, so they cannot be effectively coated with nutrient solution

Embodiment Construction

[0027] Referring to Fig. 1A, it can be seen that the tube material (1) is a slender hollow hydroponic tube (2) whose cross section is roughly oval. An etch line (3) is scored along a plane coaxial with the minor axis of the hydroponic tube (2). The etched lines (3) designate the centers of the circular orifices (4), which are equidistant from each other along the plane of the hydroponic tube (2) (FIG. 1B). The cut rounds (5) (FIG. 1C) are kept for later use in the construction of the device as shown in FIG.

[0028] The device of Figure 2 comprises a frame (6) connected on both sides by beams (7). The round block (5) is fixed on the beam (7) to support the hydroponic tube (2), for example, it can be glued or riveted to the beam, or fixed in other suitable ways. The hydroponic tube (2) is then glued to the disc (5). The inlet end (8) of each hydroponic tube (2) is inserted into a nutrient reservoir (9), which may be secured to one end of the beam (6) in any suitable manner. ...

Abstract

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.

Description

technical field [0001] The present invention relates to hydroponic equipment. The present invention finds particular, but not exclusive, use in hydroponic devices and for purposes of illustration will refer to this application. Background technique [0002] The hydroponics technique involves the cultivation of plants without soil, where essential nutrients are delivered to the plants in the form of an aqueous nutrient solution, which is delivered to the roots of the plants. Hydroponic technology offers certain advantages over conventional agriculture, including careful control of optimal liquid supply, elimination of weeds, and improved pest and disease control. However, compared with traditional agriculture, its basic investment is large. For this reason, for hydroponics to be commercially viable, it must be fairly intensive and efficient. [0003] One type of hydroponics has the roots of the plants in furrows or tubes that are irrigated with a nutrient solution, usually...
