Embodiment Construction

[0037] Different types of plants and plants at different stages of cultivation have different watering requirements. The invention enables simultaneous cultivation of a group of different groups of plants within the same hydroponic tray, in separate compartments (providing optimal irrigation according to the requirements of the plants in each compartment). This saves space and is cost effective.

[0038] In irrigation and drainage systems, the plant roots are irrigated with a nutrient solution during the irrigation phase so that nutrients and water can be absorbed by the roots, while the drainage phase allows air to reach the roots.

[0039] In nutrient film technology, a stream of nutrient solution is continuously supplied to the plant roots.

[0040] Depending on the type of hydroponic system, such as in a irrigation and drainage system, the tray 10 of the present invention makes it possible to significantly reduce the operating time of the pumps used to supply nutrient sol...

Abstract

The tray (10) of the present invention is for use in hydroponics. The tray has a first end and a second end having a longitudinal axis defined therebetween. An inlet (20) is provided at the first end for receiving nutrient and an outlet (30) is provided at the second end for draining nutrient solution. A levee system comprising paddle assemblies (40) extending orthogonal to the longitudinal axis of the tray is disposed between the first end and second end of the tray. The paddle assemblies are adapted to partition the tray to define compartments and to impede the downstream flow of nutrient solution from the first end to the second end. The paddle assemblies are adjustable so as regulate depth of nutrient solution in each compartment to enable optimal irrigation of the plants cultivated in each compartment. To complete a hydroponic system, the tray of the present invention connects to at least one reservoir for holding nutrient solution. The reservoir comprises conduits in flow communication with the inlet of the tray or outlet of the tray. Nutrient solution held in the reservoir is supplied to the tray via the inlet, and nutrient solution in the tray is drained into the reservoir via the outlet.

Description

technical field [0001] The invention relates to a hydroponics tray. More specifically, the present invention relates to a tray capable of adjusting the depth of a nutrient solution within the tray. Background technique [0002] Hydroponics is the method of growing plants using a nutrient solution without soil. Nutrients that plants normally get from the soil are dissolved into the solution. The plants are usually suspended or cultured in an inert medium, such as perlite or gravel, which provides anchoring for the roots and acts as a temporary store of nutrient solution. [0003] Flood and drain systems are common hydroponic systems. It is a system that operates in a continuous cycle consisting essentially of two phases, a filling phase and a draining phase. During the perfusion phase, a nutrient solution is delivered to the roots of the cultivated plants. After a predetermined period of time, the drainage phase begins and the nutrient solution is drained. The drainage ...
