Abstract: A hydroponic assembly in the form of a tray having spaced through-openings serving as growing stations, the tray being supported by a trough containing a body of nutrient solution. At each growing station there is a wafer of dry compressed growing medium having a seed-receiving surface on its top side and having a wick communicating with its underside and extending downwardly into the nutrient solution, the growing medium being of the type capable of expanding three-dimensionally into a porous root-supporting block as the solution is fed via the wick by capillary action. The land surface surrounding each opening is formed into a well or receptacle for maintaining the porous block seated and generally aligned with the opening. A transparent cover of hollow inverted shape defines an enclosed space developing high humidity for sprouting of the seeds and growth of the resulting seedlings, the cover, tray and trough being interfitted.

Abstract: A versatile yet highly simplified and exceptionally utilitarian plant growth apparatus assembly is comprised of a combination, in desired practical plurality, disposition and geometry and arrangement, of several individual and self-contained functional units and structures that are modular in nature and applicability and cooperable for engagement and association with one another so as to constitute the wanted and/or necessary resultant effective and operable assembly; the modular units being severally and characteristically in the nature of either mechanical structure members and/or environmental control systems electrical or otherwise in nature and/or light-providing components; the several said units further being peculiarly adapted for very quick and easy mounting and construction into, change and alteration within, addition to or disassembly from the structured apparatus assembly.
