GREEN ROOF TRAY SYSTEMS:

The Tray is a modular vegetative roof system designed for stormwater management and ease of installation. The trays are 2’x2’x4-5/8” in size. Because of the interlocking edges, excess media can be placed over the top of the tray for invisible tray edges when planted-in-place.
