Indexing plants in two-dimensional and three-dimensional space in a controlled growing environment

A crop production system for a controlled agricultural environment comprising at least two sub-assemblies, wherein, for each sub-assembly of the at least two sub-assemblies:

• a. the sub-assembly comprises a plurality of passive guides radiating outward from a central portion of the sub-assembly,
• b. each passive guide is separated from two adjacent passive guides of the same sub-assembly by respective angles;
• c. the sub-assembly is disposed coaxially with respect to another sub-assembly of the at least two sub-assemblies along an axis that passes through the central portion, and each of the at least two sub-assemblies is disposed at a different respective, non-perpendicular angle with respect to the axis,
• d. each passive guide has a first end proximal to the central portion of the sub-assembly and a second end distal to the central portion of the sub-assembly, and
• e. each passive guide is configured to guide a respective set of plant growth modules of a plurality of plant growth modules corresponding to the sub-assembly between the first end and the second end of the passive guide.
