An automated growing system comprises a plurality of vegetative production lines for moving a plurality of planted growing channels from a first end to a second end of a growing area, a plurality of flowering production lines for moving the channels from the second end to the first end, and a first conveyor belt for moving planted growing channels from the plurality of vegetative production lines to the plurality of flowering production lines. Each production line may comprise a frame, a conveyor assembly configured to receive growing channels, a fertigation delivery line comprising a plurality of regulators spaced therealong for depositing fluid into the growing channels, a drainage trough, and an air supply duct positioned under the conveyor assembly, the air supply duct comprising a plurality of openings therein for delivering conditioned air to plants growing in the growing channels. Each growing channel may comprise a trough having a first end higher than a second end, a flange extending laterally from each of a pair of opposed lateral edges of the trough and having a plurality of leach lines on an upper surface thereof extending a different predetermined distance from the first end toward the second end, and a fertigation receiving structure attached to the first end of the trough and configured to direct fluid falling therein into the leach lines of each flange.
