Modular Run to waste (RTW) table tray/base - 1m2 deep tray supports the plants in Hydroponics systems.

Run to waste (RTW) is a common horticulture term that simply means irrigation is applied to the plant until it moves through and out of the root zone and is then disposed of or used elsewhere in the garden.

In a run-to-waste system, the water or nutrients are not recirculated or recycled for reuse later. Therefore, the run-to-waste system is the opposite of a recirculating system.

Run to waste is a simple irrigation system. It can be used by flowing water through soil or another growing medium, or it can be used hydroponically.
