This mini ebb and flow tray measures 4 x 52 x 52cm and suits the Bonanza 0.35 grow box. It works as a drip tray or as a flood and drain bed. Moulded drainage channels let the tray run dry after each watering, so roots are not left sitting in standing water.
That matters because roots need oxygen, and leftover pools breed bacteria, fungi and algae. The 4cm raised edge also catches any leak water inside a grow cabinet. Good for trays of microgreens, salad leaves or propagation. A lead through is not included and is added separately.
