The Jiffy Microgreen Tray single cavity is made from recycled plastic and holds a 30cmx40cmx5cm grow plate(expanded dimensions). The trays are reusable and the system suits growers supplying restaurants or stores as new trays of microgreens can be delivered while collecting used trays.
Trays have drainage holes but once the coco plank is expanded it holds significant water and very little additional water is needed for germination. Once germinated, watering needs to be more frequent.
