A novel tissue culture assembly (10) which employs a tray (11) that presents one or more cavities (12) opening upwardly through a web sheet (13). A unique growing medium (25) is received in each cavity (12) and comprises a mixture of granulated foam (26) and pulverized gel (28). A membrane (35) spans the opening of each cavity and is secured to the tray (11). An aperture (36) pierces the membrane (35) at approximately the central portion of the cavity opening, or mouth (17), and the sides (38) of the aperture (35) engage a propagule (40) inserted through the aperture to support the propagule. The base (19) of each cavity (12) is provided with an aperture (20) by which selected fluids may gain ingress and egress with respect to the cavity. A domed cover (60) may be removably secured to the tray (11).
