WIRE KIT
Wires in the greenhouse give you new options. You can create shades by hanging light-weight curtains in a wire at the top of the greenhouse, and let the other wire hold the curtain against the glass. The wires are also a great solution as a plant support for vines and creepers.

The set consists of 2x6-meters plastic wrapped wire and brackets.
