It’s cost-effective and portable design make for a great starter tunnel and is excellent for those who frequently move it around their farm. The Gothic-style Caterpillar Tunnel (RIGHT) is an excellent choice for those living in northern climates where snow is a frequent threat. The Gothic Pro tunnel is also our most sturdy Caterpillar Tunnel available, making it an ideal choice for those with high wind environments as well.

Changing with the seasons.

Our Caterpillar Tunnels work great for starting crops earlier in the spring, and keeping them going longer in the fall. In the heat of summer you can easily push the plastic all over to one side, or take it off completely, and replace it with shade cloth to protect your crops from the summer heat.
