The Botanicare® Pallet Rack Tray 4 ft x 8 ft is designed to fit standard (42 in wide x 96 in length) pallet racking or shelving. Utilizing racking for vertical propagation allows you to take advantage of overhead space, reducing your cultivation footprint by up to 50%. Specially designed features allow this tray to sit flat on the pallet racking with a trough that hangs slightly over the edge. This trough collects runoff then directs it toward the bulkhead recess to reduce standing water. The Rack Tray is perfect for large-scale microgreen or propagation production accommodating sixteen, 10 x 20 prop flats. The 93 in length allows trays to be palletized vertically in quantities of 30 on a standard 40 in x 48 in pallet.
