Abstract

A gravity independent photosynthetic growing system (10) is provided for use in providing an environment conducive to growing plant materials under unusual conditions, such as are encountered in space or in locales isolated from sunlight. The growing system (10) includes a stationary core assembly (26), a rotating drum assembly (28) which is rotated by a motive assembly (30), an enclosing assembly (32), a growth requirements assembly (34) and a control assembly (35). Illumination lamps (42) situated in the central core (20) provide photosynthetic radiation which is transmitted through light transmissive sector walls (52) to be reflected inward from a surrounding cylindrical reflector (64) into growth sectors (50) within which the plants are grown. The growth sectors are adapted to receive seed mats (178), hard shell growth cases (204) and growth bags (188) which provide purchase for the plants. A deluxe growth requirements assembly (340) provides controlled dispensation of flowable materials by way of pneumatically controlled flow paths. The system (10) is adapted to further provide temperature and moisture to non photosynthetic plants in dark zones (174) within the stationary enclosure (24).

Claims

1. A living plant growth support system for controlled growth of plants under ambient conditions which may differ substantially from ideal, comprising:

a substrate bag having an enclosing material;

a rooting substrate disposed within said substrate bag for supporting a growing plant;

plant receiving zones disposed within said substrate bag in abutment with said rooting substrate, for receiving viable growing plant material therein; and

the viable growing plant material is selected to be in the form of seeds and said plant receiving zones include a seed cavity adjacent to a stem portal formed in the enclosing material, each seed cavity including a polymer pellet formed from powdered polymer for supporting and retaining the seed and moisture delivered thereto, so as to facilitate germination and early growth of the seed, to form an air and water-tight seal about said seed cavity through all stages of plant growth and development, and for urging the plant emerging therefrom to grow through the stem portal.

2. The living plant growth support system of claim 1 wherein

a foliage bag is provided to mate with said substrate bag such that the stem portals provide access to the interior of the foliage bag, the foliage bag being inflatable such that the interior thereof provides a volume within which foliage of the plants may grow.

3. The living plant growth support system of claim 2 wherein

said polymer pellet, said seed cavity, and said stem portal cooperate to form an air-tight and water-tight seal between said substrate bag and said foliage bag through all stages of plant growth and development.

4. The living plant growth support system of claim 1 wherein

said substrate bag includes a material transport means therewithin for transport of fluids from an exterior fluid source to said rooting substrate.
