A system for providing an enclosure system with automated light deprivation shade deployment and retraction is described. The system includes a plurality of trusses oriented parallel to each other and including at least a horizontal interior member with two diagonal members extending downwardly from ends thereof and two vertical members extending downwardly from the diagonal members on portions thereof opposite said horizontal member; a shade structure having a fixed edge fixed to one of the trusses and a leading edge; a leader arch coupled to the leading edge and including a horizontal bar extending between two or more diagonal bars at opposite ends thereof, and with vertical bars extending downwardly from the diagonal bars on portions of the diagonal bars opposite the horizontal bar; wires extending longitudinally between the truss members and along lines perpendicular to planes in which the truss members are oriented, and inboard of shade curtains.
