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 ...
