There are many styles and types of construction available on the internet. The ones mentioned in this presentation cover what is commonly available. Many suppliers carry hoop materials, row covers, and greenhouse film. Ingenuity and imagination creates more effective ways of set up and operation.
The caterpillar example in this presentation is based on low-cost materials. The tunnel is not recommended for handling snow loads. One problem found with it is that rain water can pool pockets of the greenhouse film between the cord/rope. This would require daily observations to push the water out so as not to cause bending of the hoops. Use of the tunnel should be for the extension of the season or getting an earlier start of the season making it easier to work inside. In order for the tunnel to stand up to the winter, daily maintenance is required.
A heavy duty version of the caterpillar tunnel is shown in another presentation listed on this website. It uses chain link fence poles and offers year-round operation with the stronger construction.

Upcoming Events
Niagara Region Vegetable Meeting
![Event Offers DEC Credits](../images/dec_credits.gif)
August 14, 2024
Clarence Center, NY
We'll start this meeting off at Root Down Farm to hear late season disease management updates in peppers and cole crops, plus current best management practices to limit fungicide resistance. Potato variety recommendations and disease control questions in potatoes will be addressed.
Then we'll head to Kreher's beet field to view and discuss alternative weed control technologies. The beet field is an on-farm demonstration of various flame weeding protocols in comparison with stacked tool cultivation equipment. One or two weeding robots will be on-hand for live demonstrations and discussion of the technology's current abilities and future potential. We'll also cover industry updates and a review of late summer disease management in squash.
2.0 DEC credits will be available in categories 23, 1a, and 10.
