A structure made from tubular elements which interfit to form a plural compartment hydroponic unit. The upper compartment is filled with inert root medium, houses a fluid dispensing unit, and contains slits which communicate with the lower compartment which constitutes a resevoir. The tubular housings are substantially sealingly interconnected. The lower compartment contains a nutrient inlet provision which communicates via a manifold housed in the lower compartment with the interior of the upper compartment. The lower compartment also contains a drain provision.

A device for the hydroponic cultivation of plants, consisting of: two horizontal tubes, of opaque, water-proof, and rigid plastic, sealed at their ends, of substantially equal length, the axes of the tubes parallel on the same vertical plane, that is, one tube above the other, the lower tube slotted to receive less than one-half the circumference of the upper, the length of the upper tube thus resting within and above the length of the lower; said upper tube slotted lengthwise to receive seeds, transplanted cuttings, and inert medium for the anchoring and protection of the plant roots; said upper tube containing perforated piping which parallel to the axis of the tube and covered by the inert medium, extends throughout the length of the upper tube so as to distribute nutrient solution evenly to the roots of the several plants which may be contained in the inert medium; said upper tube, the ends of the tube removable to allow cleaning; said upper tube containing perforated piping, the ends of the perforated piping removable to allow cleaning; said upper tube being slit repeatedly, the slits being parallel to the tube\s axis and extending throughout its length in the fraction of its circumference which rests within the lower tube, said slits allowing the nutrient solution distributed by the piping to the roots of the plants to drain from the upper tube, the slits also allowing the roots of the plants to grow downward so as to follow the solution draining from the upper tube; a lower tube slotted to receive the upper tube, the length of the upper tube fitting into the slot so as to create a seal excluding daylight, insects, and ambient air, the slits of the upper tube thus sealed within the lower tube; whereby a substantial seal is created to protect roots depending from said upper tube and a closed channel is defined to contain liquid draining from the upper tube; said lower tube having ends which are removable to allow cleaning; said lower tube fitting with sockets for drainage and the input of nutrient solution; said lower tube containing a pipe connecting the interior aperture of the solution input socket to the perforated pipe of the upper tube, so that nutrient solution enters the lower tube through the input socket, flows through the pipe contained within the sealed channel of the lower tube to the perforated pipe of the upper tube, the perforated pipe distributing the nutrient solution to the roots of the plants which may be supported in the upper tube, the nutrient solution flowing over the roots hanging from the upper tube, the lower tube capturing the unabsorbed solution, then channeling the solution to the drain.
