  • Patent number: 5172517
    Abstract: A special production pot includes a upstanding portion and a conical center depression for accepting lower pointed end of a plant tube. The bottom edge of the plant tube is elevated well above the top of the upstanding pot portion of the special production pot in order to provide for clearance for the plant's roots to grow in the substrate of the pot. Thus, the plant can be grown in this manner in a truck garden. When the plant has grown to a sufficient size for sale, the special production pot and plant tube is placed within a sales pot. Thus, the combined special production pot and the sales pot can be delivered to the customer.
