Plant support structure for improving canopy light exposure
A plant support structure (e.g., a grow tower) comprises a spine and grow sites (e.g., pots) coupled to the spine. Each grow site may be configured to hold a root mass of a plant, such as a micro dwarf tomato. Each grow site may be disposed above another grow site. A ratio of a width of the spine to a width of the grow sites may be less than 1.0. A harvesting system may comprise multiple plant support structures, and a superstructure from which the structures are suspended and conveyed along a grow line to a harvesting site.
1 . A harvesting system comprising a plurality of structures and a superstructure from which the structures are suspended and conveyed along a grow line to a harvesting site, each plant support structure comprising:
a. a spine; and
b. a plurality of grow sites coupled to the spine, wherein
i. each grow site in the plurality of grow sites is disposed above another grow site of the plurality of grow sites, and
ii. each grow site is coupled by a coupling to the spine so that the grow site is free to move in at least one dimension to maintain its orientation while a major axis of the spine moves from a non-horizontal dimension toward a horizontal dimension.
2 . The system of claim 1 , wherein a width of the spine is in a range of 1-3 inches and the width of the grow sites is in a range of 3-4 inches.
3 . The system of claim 1 , wherein each grow site is coupled by the coupling to the spine so that the grow site is free to move in at least one dimension to maintain its orientation while a major axis of the spine moves from an angle between 30-90 degrees with respect to a vertical dimension toward a horizontal dimension.
4 . The system of claim 1 , wherein each grow site is coupled by the coupling to the spine so that the grow site is free to move in at least one dimension to maintain its orientation while a major axis of the spine moves from an angle between 30-90 degrees with respect to a vertical dimension during a growth stage toward a horizontal dimension during a harvesting stage.
5 . The system of claim 1 , wherein a ratio of a width of the spine to a width of each grow site is less than 1.0.
6 . The system of claim 1 , each of the plurality of grow sites comprising a first irrigation line entering a top portion of the grow site and a second irrigation line exiting a bottom portion of the grow site.
7 . The system of claim 1 , wherein the spine comprises a hollow structure that has an inlet for collecting fluid from an upper grow site of the plurality of grow sites and an outlet for providing fluid to a lower grow site of the plurality of grow sites.
8 . The system of claim 7 , wherein the hollow structure comprises a tube.
9 . The system of claim 7 , wherein the inlet is connected to the upper grow site and the outlet is connected to the lower grow site.
10 . The system of claim 1 , further comprising, for each of the plurality of grow sites, a funnel for directing fluid toward a top portion of the grow site.
11 . The system of claim 1 , wherein the coupling comprises a cable, cord, or rope.
12 . The system of claim 1 , wherein a ratio of a width of the spine to the width of the grow sites is less than 0.25.
13 . The system of claim 1 , wherein structure is a grow tower.
14 . The system of claim 1 , wherein each grow site comprises a pot.
15 . The system of claim 1 , wherein the spine comprises a rigid structure or a flexible structure.
16 . The system of claim 1 , wherein the harvesting system resides in a controlled-environment agriculture system.
