A soilless culture facility includes a frame supporting a plurality of profile sections extending parallel to each other in a horizontal plane, from a transverse loading area to a transverse harvesting area, and a plurality of supports, each suitable for receiving a culture substrate. The plurality of supports are longitudinally movable in the longitudinal gap defined by two adjacent profile sections. The movable supports are moved by a motor means suitable for modifying the distance between two consecutive supports during travel in the gap. The plurality of profile sections have opaque and flexible longitudinal joining side band strips, the joining side band strips of two adjacent profile sections joining to close the gap defined by the adjacent profile sections. The movable supports have arcuate slots in the front and rear cross-sections of same, to either side of a longitudinal vertical plane, the two band strips joining at the lower edge.

A roller assembly for transporting a substrate includes a step roller and a plurality of first auxiliary rollers. The step roller includes a main roller, and a pair of edge rollers sleeved on the main roller and located on two opposite ends of the main roller, respectively. The plurality of first auxiliary rollers are disposed on two opposite sides of the step roller, respectively. A first film forms a closed loop through the first film being rolled on the plurality of first auxiliary rollers and the step roller cyclically. A method using the same is also provided.

Example insect egg conveyors are disclosed. One example insect egg conveyor device includes multiple rollers positioned along a path and a drive unit that includes a motor connected to a roller of the multiple rollers to drive the roller and rotate the roller. The device also includes a substrate positioned on the roller and a fluid source positioned along the path. The rollers are arranged to move the substrate along the path and toward the fluid source in response to the motor rotating the roller.
