Caterpillar Tunnel Kit

Do you have a large garden, for pleasure or for profit, that needs low-cost covered growing space to protect your sensitive crops from the cold and elements? Then look no further than these specially designed Caterpillar Tunnels from Greenhouse Megastore! Caterpillar Tunnel is the most affordable way to achieve temporary covered growing space. They offer protection from heavy rain, cold, wind and more to extend the growing season.

Caterpillar greenhouse tunnels are simple tubular steel structures that fix in place with simple ground anchors - no digging or drilling required. They can be taken down, moved and reused from season to season. Featuring steel hoops spaced four feet apart with a simple ridge purlin holding it all together, these caterpillar tunnels for plants can be covered in plastic to protect crops in the spring and fall. Or cover them in shade cloth to protect heat-sensitive crops like lettuce and spinach during the heat of summer.

Similar to our Low Tunnel Kits only much larger, Caterpillar Tunnel Kits are the easiest, least expensive way to get growing footage under cover. They're available in a 16-foot width and two lengths - 24 feet or 48 feet - with 6 mil poly film and all hardware you need. Tunnels can be connected for a longer greenhouse run, and if you'd like to order custom caterpillar tunnels, call us or complete the request form. You won't regret your investment in this incredibly-priced growing space! Greenhouse Megastore guarantees the lowest price on commercial-quality plant structures.
