These one piece lids are ideal for use in spawn production and are superior to metal canning lids in that they will not rust or warp. One or two 1 inch diameter holes should be drilled through each (a 1 inch hole saw works well for this purpose) and a filter disc inserted underneath to allow contaminant-free air exchange. Color: various.
