A pad (16) of open celled fully reticulated polyurethane foam which is substantially hydrophobic serves as a bed for growing sprouts (14) from seeds (12). A high percentage of interconnected voids in the pad (16) provide a high degree of permeability to air flow and the material has surface properties, which retain adhered droplets of moisture providing humid environment without holding localized moisture which might prevent the free flow of air through the pad. The bulk of any applied water or mist is drained through or away from the pad, thus flushing impurities from it. A loose cover sheet of film (15) helps retain a humid atmosphere and pad (16) may be wrapped in such a sheet (18) to package the sprouts (14). The pad (16) may be transferred to a shipping tray (34) after the seeds are sprouted or may be originally placed in it. The pad (16) and tray (34) may have an extended lip (38) for collecting moisture when the package is inclined on end to provide optimum conditions during storage. A portable germinating device (10a or 10b) includes layers of the aforementioned pad (16a or 16b) within a shallow dish (34a or 34b) and cover (42a or 42b) having variable apertures (54a) through which water and air may pass.

A seed-germinating combination for growing sprouts from seeds, comprising a pad of porous material supporting a layer of germinating seeds, the pad having a three-dimensional structure of a substantially hydrophobic porous material which is substantially nonabsorbent and having a very high percentage of interconnected voids giving it a very high degree of permeability to fluid flow, the voids providing pores ranging approximately from 8 pores per inch to 50 pores per inch, the porous material having surface properties which in conjunction with the stated pore concentration and size retains droplets of moisture disposed therein sufficient to provide a humid growing environment without retaining localized water in an excess which can promote decay or block free flow of the water and moisture through the pad, and the pad is held on an open support whereby most of any water applied to the pad is caused to flow through and drain out of the pad.
