my tray consists of a large tank with pump underneath, the gently sloping tray, covered by a plastic sheet with holes in for the plants. my plants are in rockwool cubes
the tray is crosshatched with channels for the water to trickle down from the left side to the right.

its hard to describe so i will try to upload a picture of it
