This is a smart table top system designed by Osprey. This is basically a 4 wire system principally for strawberry production. However, the design is used in other cultivars that carry growing substrate bags, troughs pots and normal pots.
4 wires are tensioned to the strain of piano wires using a clever tensioning design by Osprey and creates the perfect low cost table top system.
