Abstract
An open tubular element or container is designed for retaining plants, seedlings and dirt to enhance the cultivation and growth of plants and to automate the filling of containers with dirt and seedlings. The device includes two generally semi-cylindrical body sections, each of which has an upper integrally connected or separably attached semi-circular panel. Each of these panels includes a semi-circular opening and includes an upwardly extending semi-cylindrical funnel portion, so that when the semi-cylindrical body portions are joined to each other the semi-cylindrical funnel portions will form a cylindrical funnel which is coaxial and concentric with the outer periphery of said tubular body sections. A drainage opening is provided in a bottom panel and is formed by mating semi-circular openings in semi-circular panels attached to lower ends of each of said semi-cylindrical body sections. The lower opening is provided to drain water and other liquid outwardly from the bottom of the container. This tubular container provides for mechanizing both horizontal and vertical filling of the containers formed by the semi-cylindrical sections.
