Super Sprouter Quad Thick holes

These reusable trays are built tough for long lasting durability! They are injection molded, where as most 10 x 20 trays are vacuum formed. They are four times the thickness of regular 10 x 20 trays. No need to use multiple trays to gain strength when one quad thick tray will do the trick. The tray insert has a perforated bottom for easy drainage.
