1020 Black Tray. No Holes. Quad Thickness Heavy Duty. Super thick & sturdy. Alternative solution to Permanest Trays (11 x 22) as they fit with regular 1020 propagation domes. Plastic material is stronger to support heavier loads. Flexible, not hard rigid plastic so it bends/gives a little rather than cracks like thinner 1020 trays or Permanest Trays.
 
1020 Tray Propagation Dome. 2" Tall. Clear.
