Air Tray® Technologies were developed and field-tested to optimize and extend the benefits of the Air Tray® by streamlining production manufacturing for our grower partners. This 50 count tray takes a 40mm X 90mm Ellepot. It’s great for tree production where a smaller size cell is desired. Trees started from seed or cuttings in this tray can be transplanted to a larger container or go straight to the field. The smaller cell and higher density tray make it economical too.
