Mondi 1020 Propagation Tray Sandwich Support

This is a little support stand I made last night to prevent the classic 'stuck propagation trays' problem I face when nesting the propagation tray with holes inside the propagation tray without holes. It lifts the inner tray without blocking the holes, allowing for increased drainage and gas exchange. Specifically designed to help minimize anaerobic zones while using the nested propagation tray method. Designed to fit Mondi 1020 propagation trays. Will probably work on any 1020 propagation tray
