Our Wiggle Wire upgrade kit helps turn your Caterpillar Tunnel into a more permanent greenhouse solution. Wiggle wire allows you to have tighter plastic, or help hold down shade cloth on your Caterpillar tunnel. In most cases, we recommend pairing Wiggle Wire with our Wind Bracing upgrade kit, allowing for increased wind protection, plus eliminating the need for the cone-shaped plastic bunching at each end of your tunnel. This is especially helpful on urban farms or other situations where space is limited.
The Wiggle Wire upgrade contains 8’ of base channel and 8’ of wiggle wire. For typical installations we recommend 4 sets, allowing for two sets of Wiggle Wire and channel on each end bow. If you want the Wiggle Wire to extend all the way to the ground, you will need 6 sets (3 for each end bow).
Recommended quantities for framed-in end walls are as follows:
6 sets (3 for the top edge of each end bow)
6 sets (3 for the door and 3 for the frame)
For example, if you put an end wall with doors on both ends, you will need 18 sets of wiggle wire and channel. Additionally, because wiggle wire is expensive to ship by itself, we recommend purchasing them with a freight order, and padding the amount slightly. If you have a local source, that could work out better for you as well.
Note: The way you frame in your end and the entry system you use will affect how many wiggle wire sets you need. Our recommendations are general in nature and ultimately the amount needed will depend on your plans/context.
