Unmatched Strength
Our Strongest Tunnel Yet
The Guardian High Tunnel's bows are 20% larger in diameter than those of our Haven High Tunnel, which makes the bows 70% more resistant to bending, significantly enhancing the Guardian's structural integrity. And just like the Haven, all Guardian bows are made with our strongest 14-gauge steel which is 40% thicker than standard 17-gauge bows.
With our strongest bows spaced every 4 feet, reinforced trusses, and additional bracing throughout—including an additional third wind bracing piece on each corner—the Guardian offers unparalleled peace of mind on windy and snowy nights. With the Guardian watching over, your crops—and your dreams—are in good hands!
Roll-Up Sides + Sidewalls
No Bending Required
The Guardian's 6.5-foot vertical sidewalls are the tallest we’ve ever offered—by almost double! No more bending over or feeling cramped when working on your outer growing beds.
In addition to allowing you to use your growing space more efficiently, the high sidewall design paired with the geared roll-up side cranks allow you to easily adjust ventilation for truly massive amounts of airflow. It's a win-win for your back and your brassicas!*
*ventilation is also effective with crops not in the Brassicaceae family
Maximize your Investment
Two Guardian High tunnels will cover the same growing space as three 14-ft wide tunnels. This allows you to reduce the number of end walls and effort needed to ventilate the same amount of growing space by 33%.

Frequently Asked Questions
Tech Specs
The Framed Double Zipper End Wall and the DIY End Wall have new 21-ft wide variants that work great with our larger tunnels like the Guardian and the Caterpillar Tunnel Max.
The Guardian High Tunnel only comes in a Gothic (peaked) roof style. We currently do not have plans to offer a Classic option in the future.
It depends on the width of your pathways. You can comfortably fit 6 beds with 12” pathways, and you could even manage to fit 7 beds with 8.5” pathways if you think the juice is worth the squeeze.
No. But each Guardian will include several extra feet of plastic to give you enough extra wiggle room for easy installation. All of our end wall options will come with enough plastic to complete your door.
Thanks to the thicker diameter pipes, industry leading 14-gauge metal, reinforced wind bracing and trusses, and metal baseboards, the Guardian is our strongest tunnel to date. We routinely hear of Caterpillar Tunnels (our least-permanent tunnels) surviving 50+ mph wind storms, and we have yet to hear of a Haven High Tunnel sustaining any wind damage—despite many being in the path of recent hurricanes—and the Guardian will only exceed those in strength. If you want the absolute highest peace of mind, consider adding concrete to some of your ground posts during installation. Lastly, check out this article on Caterpillar Tunnels and wind over on our knowledge base for more general about tunnels and wind resistance.

The Guardian High Tunnel is shipped on a 4×8 wooden pallet via motor freight (an 18 wheel tractor trailer). Depending on the order, sometimes multiple Guardians can fit on one pallet, and sometimes our longest Guardians may need up to two pallets.
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.

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/or and remove the plastic 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 $100.
To take advantage of this extended warranty, we kindly request that you complete a simple product registration process. Rest assured, the registration process is straightforward and hassle-free. All we require is your contact information, purchase details, and a few photographs of your high tunnel. This can be completed here.
Activate your ten-year warranty by visiting our website or contacting our dedicated customer service team. Our professional and friendly representatives will guide you through the registration process, ensuring a seamless experience. Please have your high tunnel photographs ready for submission. The registration process must occur within 60 days of installation.
Once your high tunnel is registered, it will be safeguarded against storm damage for the next ten years. This comprehensive coverage encompasses damage caused by strong winds, hailstorms, and other severe weather events. Normal wear is excluded from this coverage.
In the unfortunate event that your high tunnel experiences storm damage, simply reach out to our customer service team to initiate the claims process. Our knowledgeable staff will provide you with the necessary assistance and guidance. When filing a claim, please include detailed information and photographs of the damage incurred. Tunnels with an active storm damage warranty will be eligible for a 50% price reduction for any replacement parts needed to repair the tunnel, plus free shipping. Tunnels without an active storm damage warranty will not be eligible for this discount and replacement parts will be provided at full price.
Upon receipt of your claim, we will meticulously assess the damage based on the photographs provided. If the damage falls within the scope of the warranty, we will promptly proceed with the required repairs or replacement. Labor or crop loss will not be covered. Rest assured, throughout this process we will maintain clear and open communication with you to ensure a satisfactory resolution within these guidelines.
Please note that our warranty is non-transferable and remains tied to the original owner for the duration of the ten-year coverage period. Should you require any clarification or have inquiries regarding the warranty terms, our customer service team is available to assist you.
