Abstract

An apparatus for growing vine crops in a greenhouse comprises a first media carrier, a first nutrient supply means, a first support means, a regulating mechanism, a main cable, a plurality of load differential mechanisms, a second media carrier, a second nutrient supply means, and a second support means. The second media carrier is above and in substantial parallel with the first media carrier. The distance between the first media carrier and second media carrier is adjusted by the regulating mechanism. A method for growing vine crops in a greenhouse comprises two growing modes: a single crop growing mode, and a vertical dual crop growing mode. The sequence of this process begins with a first single crop growing mode, followed by a vertical dual crop growing mode, and then followed by a second single crop growing mode. A single crop growing mode: first crops grow in the first media carrier fed by the first nutrient supply means, trained by the first support means. A vertical dual crop growing mode: the first crops grow in the first media carrier fed by the first nutrient supply means trained by the first support means; and second crops grow in the second media carrier above the first media carrier fed by the second nutrient supply means and trained by the second support means.

Claims5

Dependent claims

Apparatus for use in a greenhouse having an overhead frame structure and a transparent cover for simultaneously growing two generations of seasonal plants to produce crops comprising:

a first media carrier bearing a first generation of plants and growing media for providing nutrients to said plants;
a second media carrier bearing growing media on which a second generation of plants grow;
the second media carrier being located above and substantially parallel to the first media carrier;
a regulating mechanism operatively associated with the overhead frame structure and the second media carrier for controlling and varying the vertical distance between the second media carrier and the first media carrier,
at least one elongate flexible load supporting member connected at one end to the regulating mechanism and the other end to the second media carrier;
and
at least two load differential mechanisms supported by the overhead frame structure;
said load differential mechanisms including a drum portion defining a generally cylindrical surface, and
a portion of the flexible load supporting member intermediate said ends encircling and engaging the surface of the generally cylindrical drum whereby the regulating mechanism reacts a force in the elongate flexible member that is less than the load applied at the other end of the elongated flexible member by the second media carrier,
said load differential mechanisms being responsive to the force at the first end of the load supporting members applied by the regulating mechanism to maintain or selectively lower the second media carrier with respect to the overhead frame structure and the first media carrier thereby allowing variance of the vertical position of the second media carrier with respect to the first media carrier thereby compensating for reduced growth and production of crops by the first generation of plants and facilitating growth and increased production of crops by the second generation of plants.

Apparatus for use in a greenhouse having an overhead frame structure and a transparent cover for growing seasonal plants to produce crops comprising:

a first media carrier bearing a first generation of plants and growing media for providing nutrients to said plants;
a first nutrient supply for supplying a nutrient solution to the first media carrier;
first plant support strings located between the first media carrier and the overhead frame structure for supporting said first generation plants during growth thereof,
a second media carrier bearing growing media on which a second generation of plants grow;
the second media carrier being located above and substantially parallel to the first media carrier;
a second nutrient supply for supplying nutrient solution to the second media carrier;
second plant support strings located between the second media carrier and the overhead frame structure for supporting said second generation of plants during growth thereof;
a regulating mechanism operatively associated with the overhead frame structure and the second media carrier for controlling and varying the vertical distance between the second media carrier with respect to said first media carrier,
at least one elongate flexible load supporting member connected at one end to the regulating mechanism and the other end to the second media carrier;
and
at least two load differential mechanisms supported by the overhead frame structure;
said load differential mechanisms including a drum having a generally cylindrical portion defining a surface, and
a portion of the flexible load supporting member intermediate said ends encircling and engaging the surface of the generally cylindrical drum whereby the regulating mechanism receives and reacts a force that is less than the load applied at the other end of the elongated flexible member by the second media carrier and selectively maintains or reduces the vertical separation of the second media carrier with respect to the overhead frame structure and said first media carrier.
