Production facility layouts for automated controlled environment agriculture

A crop production system for controlled environment agriculture, comprising:

• a controlled growth environment substantially encapsulating a plurality of grow lines, each of the grow lines comprising
• a grow conveyance mechanism;
• and
• a plurality of grow towers, each of the plurality of grow towers vertically attached to, and moveable along, a respective one of the one or more grow lines;
• wherein each of the one or more grow lines comprises
• a first path section, a second path section;
• and
• a return mechanism operative to transfer grow towers from the first path section of a grow line of the one or more grow lines to the second path section of the grow line;
• wherein the grow conveyance mechanism conveys grow towers along the first path section in a first direction, and along the second path section in a second direction opposite the first direction;
• wherein the plurality of grow lines are arranged in a one-dimensional array such that each grow line of the plurality of grow lines is adjacent to at least one neighboring grow line of the plurality of grow lines;
• a plurality of injection points, wherein each injection point of the plurality of injection points corresponds to a particular grow line of the plurality of grow lines;
• a plurality of extraction points, wherein each extraction point of the plurality of extraction points corresponds to a particular grow line of the plurality of grow lines;
• wherein each of the injection points of the plurality of grow lines are arranged along a line extending in a first direction proximally to a first side of the encapsulated growth environment;
• and
• a transfer mechanism comprising a carriage disposed on a track and a control system;
• and
• wherein the control system, for a grow line of the plurality of grow lines, is configured to cause the transfer mechanism to convey the carriage including a grow tower to the injection point of the grow line and insert the grow tower on the grow line, and to cause the transfer mechanism to convey the carriage including a grow tower from the extraction point of the grow line.
