Abstract: A multi-level vertical farm comprises a lift apparatus configured to carry growth trays from a bottom to a top position adjacent to a conveyor. The conveyor is configured to transport trays downwardly to near the bottom position and normally is fully loaded with adjacent trays along the entire conveyor. A growth tray in the lowest, bottom position is discharged out of that position to an irrigation or harvesting station. The discharge of a tray from the bottom position causes preceding trays to move downward, thereby opening a space in the top position for another tray, which may be lifted there. A computer system may be connected to the apparatus and programmed to start a motor of the lift apparatus to move the growth trays. The apparatus enables simulating a day-night plant growth cycle and using thermal convection to apply more warmth to higher positions, in a compact vertical arrangement.
