Dillen's 4.5-Inch Square Deep Press Fit Pot offers a cleverly designed pot that is durable, cost-efficient and high-speed automation capable. Plants fare well, thanks in part to the multi-level drain holes and a dual color layer that protects plant roots from the sun. The polypropylene construction helps control costs while remaining durable, with a strong rim for use in automation. Measure five inches high and sold by the case of 375.
