Light weight, very sturdy, UV-resistant black plastic grid for mounting orchids, ferns, air plants, bromeliads, etc. Long-lasting and will not grow mold, algae, rot, or decay like cork or wood slabs. Measures 2.5" W x 8" L x 0.25" thick, with 50 holes. The grid can be cut into two 4-inch lengths to mount miniature orchids or other small plants. We recommend using a thin layer of sphagnum moss or sheet moss as a base and fasten the plant with a cable zip tie through the holes in the grid. Roots will grow into the grid and eventually become solidly attached. Mount can be hung by attaching an S-hook or coated wire (not provided) into one of the pre-drilled hole on top and bottom.
