The Super Sprouter® AirMax™ Tray Inserts provide outstanding drainage and aeration to clones and microgreens grown in 1020 flat mediums. These mesh tray inserts are designed to allow high levels of oxygen to enter the root zone in your clone trays, helping to maximize root growth and minimize damping-off in young clones and seedlings. By elevating plants above the propagation tray’s bottom surface, the AirMax tray insert allows excess water to run off and holds plants above standing water. This helps to avoid oversaturated roots and promote proper drainage and airflow. Its low profile provides clear visibility to root development and unrestricted access to cuttings for proper care and monitoring without disturbing delicate plants.
