New Length Options

25-ft Tunnels are Back!

Perfect for backyard growers, urban farmers, and market gardeners who are looking for a space efficient propagation house or smaller growing space, the new 25-ft Caterpillar Tunnel is everything you love about easy to build caterpillar tunnels all in a new convenient size!

All 25-ft tunnels now come with 55-ft of greenhouse plastic (up from 32-ft) so you have plenty of extra plastic for the standard cone-shaped ends, or to use in alternate end wall coverings.

Year-Round Crop Protection

Caterpillar Tunnels are often viewed pri­mar­i­ly as a sea­son exten­sion tool, but that’s real­ly only half of the sto­ry. Covered grow­ing space pro­vides year-round pro­tec­tion for your plants from things like rain, pests, frost, heat (when using shade cloth), wind, and even from dirt being splashed onto your plants in heavy down­pours.

This is my fourth tunnel from Farmers Friend and every one has been well worth the price. Having everything come at once and no trips to the hardware store is wonderful.

New Tunnel Options!

Wider, Stronger Tunnels Now Available!

Max out your farm with the thick­est gauge steel Caterpillar Tunnel on the mar­ket! We now offer a 16-ft wide tun­nel (up from 14 ft) with 40% thick­er, 14-gauge steel bows (up from 17 gauge).

With steel strength typ­i­cal­ly found only in com­mer­cial high tun­nels, these 14-gauge tun­nels are designed to give you greater peace of mind on stormy nights. Plus, being 2 feet wider, you’ll have plen­ty of room for 18-inch path­ways to more eas­i­ly trans­port har­vest bins/totes, or if desired, shrink your path­ways to 10 inch­es and fit five 30-inch grow­ing beds.

Gothic Tunnels

The Perfect Tunnel for Northern Growers!

Perfect for north­ern cli­mates with fre­quent snow­fall, the Gothic (pic­tured) will allow you to grow longer into the win­ter than a Classic Tunnel. This new tun­nel also includes a sol­id purlin and wind brac­ing to add even more rigid­i­ty to your structure.

For extreme win­ter grow­ing, upgrade to the Gothic Pro, which includes a Solid Purlin, Wind Bracing, Cross Bars and 16-inch Lift Kit for added strength and height.

5 out of 5 stars

Amazing Tunnel! Very pleased!!

I just want to say how happy I am with the Gothic Pro Tunnel we purchased. With the Pro package it has a lot of added support with the wind bracing and cross bracing. We had 50 mph winds yesterday during a storm and I’m so happy I went with the Pro package for the added support. Very pleased with the product! Definitely a game changer for our farm and is so enjoyable to have protected space to grow food in!

Classic vs Gothic

The Classic tun­nel (LEFT) is cost-effec­tive and portable. It’s a great starter tun­nel and is excel­lent for those who fre­quent­ly move it around their farm or where wind is a greater problem than snow. The Gothic tun­nel (RIGHT) is an excel­lent choice for those liv­ing in north­ern cli­mates where snow is a fre­quent threat.

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.

We love our high tunnel!

We put our Gothic tunnel up last Spring, this was our first winter, and it has withstood snow, freezing rain, and high winds like a champ. We look forward to a second one, hopefully this Fall.

NRCS specifications

Our tun­nels meet the basic 325R National NRCS spec­i­fi­ca­tions. Ultimately, you should con­tact your local NRCS rep and pro­vide our instal­la­tion man­u­al found at the top of this page and the spec sheet(s) attached to our knowl­edge base arti­cle, “Do your tun­nels meet NRCS spec­i­fi­ca­tions?” for their review. Also, check out the NRCS guide below for step by step instruc­tions on how to apply!

NRCS Documents and Guides

Delivery

The Caterpillar tun­nels are shipped on a 4×8 wood­en pal­let via motor freight (an 18 wheel trac­tor trail­er). Depending on the order, some­times mul­ti­ple tun­nels can fit on one pallet.

You will receive a pro num­ber for track­ing from Farmers Friend when your ship­ment is picked up from our facil­i­ty. It is rec­om­mend­ed that you con­tact the car­ri­er pri­or to deliv­ery to make arrange­ments for time and date. There is some flex­i­bil­i­ty in date and time of deliv­ery, but cus­tomers in remote areas should accept deliv­ery at the car­ri­ers con­ve­nience to avoid exces­sive delays or extra charges.

Unloading

Prior to mov­ing or unload­ing, please take pic­tures of the order. This is in case items are miss­ing or dam­aged we have a way to ver­i­fy con­tents and con­di­tion. We rec­om­mend con­duct­ing an inven­to­ry of the ship­ment with your includ­ed pack­ing list as soon as pos­si­ble after unloading.

As far as unload­ing, it is the cus­tomer’s respon­si­bil­i­ty. The car­ri­er will not have a fork­lift to unload. A fork­lift or trac­tor with forks is not required, as the ship­ment can be unloaded by hand with two peo­ple. Simply break the bands and remove the pack­ag­ing. The indi­vid­u­als unload­ing should be capa­ble of team-lift­ing 130 pounds. Out of con­sid­er­a­tion for the car­ri­er, we request you pre­pare to unload as quick­ly as possible.

Farmers Friend will not autho­rize the use of any lift­gate ser­vices, and they are not includ­ed in any ship­ping charges, nor is it includ­ed with free ship­ping. If the local ter­mi­nal or dri­ver offers lift gate ser­vices, do not accept them for any rea­son as there will be an addi­tion­al charge billed to you from Farmers Friend at $150.

Wind Rating

There is no offi­cial wind rat­ing on our tun­nels. The cater­pil­lar tun­nel is designed to be a move­able struc­ture. Therefore, it is inher­ent­ly not made to with­stand high winds.

A tun­nels abil­i­ty to with­stand wind is based on at least 6 factors:

  1. Soil type
  2. Water Saturation
  3. Bracing
  4. Anchoring Selection
  5. Wind Direction
  6. Customer Installation

Soft soils have less grip on the anchor­ing mate­ri­als, while more com­pact soils hold better.

Related to soil type is ground sat­u­ra­tion. How wet is the soil at the time of said wind event? Saturated soil will be more like­ly to let go of the anchors.

The stan­dard cater­pil­lar tun­nel is sta­bi­lized by a nylon purlin strap. Accessories that increase rigid­i­ty while main­tain­ing the cater­pil­lar attribute of move­able are: Solid Center Purlin, Wind Bracing, and Spring Wire.

Anchoring options that exist for cater­pil­lar tun­nels are rebar, cement­ed ground posts, and Earth Anchors. Rebar is the most eco­nom­i­cal indus­try stan­dard effec­tive in mod­er­ate winds. Cemented ground posts elim­i­nates the Caterpillar Tunnel strength of tem­po­rary, but pro­vides a rock sol­id foun­da­tion. Earth Anchors are an expen­sive ground screw option that holds like con­crete but is eas­i­ly removed and reused.

Tunnels have also been report­ed as hav­ing prob­lems with the plas­tic being blown to one side from broad­side winds. Spring wire is a solu­tion to aid in pre­vent­ing this occurrence.

Customer instal­la­tion is the final fac­tor. Assuming all instruc­tions are fol­lowed and instal­la­tion is cor­rect, the stan­dard tun­nel can with­stand light winds and mod­er­ate gusts.

With all that said, our stan­dard tun­nels have with­stood winds up to 50+ miles per hour. In the cas­es where sim­i­lar winds have dam­aged tun­nels, the six fac­tors must be analyzed.

The pru­dent grow­er would do well to eval­u­ate these six fac­tors in light of their bud­get, short and long-term farm plan, and spe­cif­ic grow­ing context.

Love these hoophouses

Sylvester F.21 days agoVerified buyer

This is our 4th Gothic Tunnel hoophouse and we love these tunnels but more so, the customer service Farmers Friend provides is unmatched. We will continue to support them for their great service and quality of products they provide. Thank you for all your work to help extend our growing season.

Great cat tunnel

5 out of 5 stars

Diana L.about 2 months agoVerified buyer

Love this thing, wish I had bought it years ago. I have the 14’ by 35’ one (I added on some parts to get the extra 10’) and it is much sturdier than I anticipated, even before adding crossbars, wind braces, used extra crossbars as windbraces, endwalls and added weights along the bracing. I live in a windy area and have had structures get damaged before. I did it mostly by myself, never have built much before. Plastic was easy to get on with one person and some heavy duty clips- used those at the top to secure it and then went from there. Added my own endwalls using the extra plastic, 2 by 4s, and adhesive zippers. The instructions were very clear- only thing I would say is that it DEFINITELY took more than 3-4 hours to put up. Took me more like 20 with the endwalls. I was missing 4 ez clips but called and got them the next day. I’d definitely buy another kit!

Mud season

5 out of 5 stars

Dean T.about 2 months agoVerified buyer

Our Caterpillar Gothic tunnel arrived on one pallet perfectly wrapped. Unfortunately for us Mother Nature is not giving us the spring weather , instead snowstorms have been adding to mud season. We are very anxious to get it set up but we need a solid month to dry out. At that time I will add to my review.

Easy to assemble, sturdy structure, easy delivery

Kelsey P.2 months agoVerified buyer

This is our first ever high tunnel/greenhouse, so keep that in mind. We ordered the 50foot gothic pro, with one framed double zipper end door. the end door instructions... could be a tad bit clearer, as in, in the tunnel instructions each page showed what parts/tools would be needed for that set of instructions. all in all, we figured it out and had the whole thing, including the door, built in two days(again, this is our first ever one of these. getting the plastic on looks way, way easier on the youtube video, we wish we had another set of hands just for that part, but we did it, and one day later the whole thing survived 60mph gusts perfectly!)

The best customer service helped through missing tunnel items

Anastassia Z.3 months agoVerified buyer

My pallet was broken apart when I recieved it, and was missing the wind bracing and the associated hardware. I also had mis manufactured clamps for the top center purlin (2 of them). When I called farmers friend about these issues they quickly sent out the missing/correct pieces for my Gothic pro. It did take longer to put up than I had originally anticipated, but they company made things right, and their staff are polite and very kind. This is my 4th tunnel purchase from them.

LOVE these tunnels!

We just purchased our 3rd and 4th Gothic pro tunnels. With two people, these are an easy setup, probably 15 hours for each tunnel, and they look great! Excited to get these up and planted for the new season!

Great season extension

4 out of 5 stars

Shannon H.3 months agoVerified buyer

These tunnel kits are an easy solution when money is tight and a quick season extension solution is needed. They serve their purpose. This was my 2nd & 3rd purchase of a gothic tunnel from FF. I took a star away because there was a step missing from the pamphlet of directions that had me scrambling. Luckily I kind of remembered how it was supposed to go from the first build a couple years prior. The build is pretty intuitive, but still. I tried finding the corresponding video but the website & videos are inaccessible on Saturdays. Which is when so many farmers - especially part-time farmers - are building/working. It baffles me.

Heavy Duty/Install Process

5 out of 5 stars

Ariel P.7 months agoVerified buyer

Purchased a 14x100' Gothic tunnel. I watched many of the videos in advance as well as watching some of the youtube reviews years later. Overall I am very impressed. I think ultimately Farmers Friend has it figured out. I was never short anything. Being that I did not have an entire couple of days to dedicate to building the greenhouse all at once, I watched the install videos many times for each step I was completing. The videos are fantastic- if I'm being honest we didn't open the manual at all. I have previously ordered the overhead irrigation system for an existing structure and have loved that as well. This will be the first of many of these greenhouses as I plan to order at least two more next season.
