One variation of a method for automating transfer of plants within an agricultural facility includes: dispatching a loader to autonomously deliver a first moduledefining a first array of plant slots at a first density and loaded with a first set of plants at a first growth stagefrom a first grow location within an agricultural facility to a transfer station within the agricultural facility; dispatching the loader to autonomously deliver a second moduledefining a second array of plant slots at a second density less than the first density and empty of plantsto the transfer station; recording a module-level optical scan of the first module; extracting a viability parameter of the first set of plants from features detected in the module-level optical scan; and if the viability parameter falls outside of a target viability range, rejecting transfer of the first set of plants from the first module.

A sunlight modulation device includes a light focusing module and a light deflection module. The light focusing module is configured to let incident sunlight pass through and to converge direct sunlight of the incident sunlight. The light deflection module is configured to separate the converged direct sunlight from diffusion sunlight of the incident sunlight by reflecting the converged direct sunlight. The above-mentioned sunlight modulation device allows more diverse configurations for solar panels, heating devices or the like means, as well as illumination purpose.

A cultivation floor system with a floor includes a watertight basin with a watertight groundsheet, a water-permeable structure in the basin, and a permeable top sheet which lies substantially horizontally over the water-permeable structure and forms the top side of the floor on which plant containers are optionally placed. The basin has a water-barrier structure which protrudes above the floor and delimits the compartment which is present on the floor. The water-barrier structure includes a horizontal beam with a top side, a water-barrier profile with a bottom side, and fastening means which fasten the water-barrier profile to the horizontal beam. The top side of the beam is substantially level with the top side of the floor formed by the permeable top sheet. The bottom side of the water-barrier profile is pulled onto the top side of the horizontal beam while clamping the watertight groundsheet and the permeable top sheet.

A threshold level setter/water content index detector calculates an Ln (I.sub.905/I.sub.1550) which is a total sum of the reflection intensity ratio as a water content index of one leaf. A controller displays a graph representing the time-transition of the water content contained in the leaf of the plant from the start to the end of the measurement period on a UI screen of monitor 50. The controller fixedly determines and sets, as a leaf, a set of reflection positions where the water content for each reflection position which is calculated at the start of the measurement period exceeds a threshold level. When viewed from first beam source and second beam source, white reference substrate which covers a back surface of the leaf of the plant is disposed on the leaf of the plant.

A system for utilizing waves in an assembly line grow pod includes a plurality of carts, a wave generator and a master controller. The plurality of carts carries a plurality of plants including a first plant and a second plant. The wave generator generates sound waves having a different range of frequency. The master controller is communicatively coupled to the wave generator and comprising a processor and a memory storing a wave recipe and instructions. The wave recipe correlates the plurality of plants with different characteristics of sound waves including frequency. The wave generator generates a first sound wave having the characteristic correlated to the first plant and a second sound wave having the characteristic correlated to the second plant.

A pressure control system includes a sealed area containing one or more carts for growing plant material, the one or more carts movably supported on a track within the sealed area, an air pressure controller operably coupled to the sealed area such that the air pressure controller controls an air pressure within the sealed area, and a controller. The controller includes a processor, a data storage device storing one or more pressure recipes, and a non-transitory, processor-readable storage medium comprising one or more programming instructions stored thereon. The one or more programming instructions, when executed by the processor, cause the processor to: identify the plant material in the one or more carts, retrieve a pressure recipe for the identified plant material from the data storage device, and direct the air pressure controller to adjust the air pressure within the sealed area based on the pressure recipe for the identified plant material.
