Benefits of Plastic Tunnels

A greenhouse, or high tunnel as this style is more appropriately called,
effectively moves your production space one USDA growing zone closer to the equator.

This means that your crops will experience a warmer climate, as well as protection from adverse
weather events. Both these features enable you to grow more crops, faster, and for a longer portion of the year.

We can build many styles of structures to best suit your needs.

3 Different door options

Wind Bracing

Lift Kits

Center Purling Upgrade

Assembly Upgrade

We offer two styles of tunnel shapes

Quonset

This classic design is simpler to construct and so cheaper to install.

The main advantage of Quonset style greenhouses are their freestanding architecture, which lets in the greatest amount of sunlight of any greenhouse design

Gothic

In addition to the sweet style points, this design really helps the tunnels shed winter snow loads.
The price of this option can vary greatly depending on the size.
Additionally, we highly recommend a number of structural upgrades if you’re concerned about snow on your tunnel.

End-walls & Doors, doors, doors!

All tunnels close with a gather-and-stake style with the plastic, gathering it together
and staking it ~10’ beyond the last rib of the tunnel. This gives the end-walls of the tunnels
incredible wind resistance, but can impede access to into the tunnel.

You can upgrade any tunnel to have a flat end-wall with a few different door options.But, this requires upgrading wind bracing to the tunnel as this style is pushed harder by the wind.
Every tunnel has two ends, and each single door costs as follows:

Gather-and-stake
FREE
Single-zipper end-wall
$ 640
Double-zipper end-wall
$ 650
Fully-framed door
$ 2000

Doors can affect the structural integrity of the build.
Using a single door requires the use of partial wind bracing: see below.

Double-zipper

Gather-and-stake

Wind Bracing

This is additional bracing for the flat sides of the tunnel. It’s not often required in the Willamette Valley, but might be in your specific location.
These braces also help the rigidity of longer tunnels.

Wind bracing on both sides
$ 240
Wind bracing on one side
$ 150
This is additional bracing for the flat sides of the tunnel. It’s not often required in the Willamette Valley, but might be in your specific location.

These braces also help the rigidity of longer tunnels.

Lift Kits

Lift kits raise the entire tunnel another 16″ off the ground. This gives you and your crops valuable headroom. Plants can grow higher. Your tunnel traps more air for greater insulation.

Tunnels <50'
$ 280

Upgrade to a heavier gauge (for windier or snowier conditions, or heavy crop load tied to the tunnel structure) || +$20

Tunnels 51-100′
$ 540

Heavier gauge (for windier or snowier conditions, or heavy crop load tied to the tunnel structure) || +$40

Center Purling Upgrade

Swap out the fabric purlin strap for steel purlins. This dramatically increases the structural stability of your tunnel. This improves wind resistance, snow load capacity, and even just trellising plants onto the overhead structure.

50’ and under
$ 320
51-100’
$ 630

Assembly Upgrade

We swap out the self-tapping screws for a drill and some bolts! We pre-drill all the connection points and secure them with nuts and bolts. This adds tremendous rigidity and life to the structure. This is particularly useful if you intend to be putting the tunnel up and down with any recurring frequency.

50’ and under
+ $ 480
51-100’
+ $ 790

The Installation Process

Schedule a meeting

First, please schedule a short (15-minutes or less) consultation meeting via phone or Zoom.This consultation is the necessary first step in figuring out the details needed to set up your greenhouse for long-term success.

Get a rough estimate

In this meeting we will explore your wants and needs from this structure as well as details about the location for its installation. You will receive a rough estimate by the end of the meeting for you to consider.

Pay a deposit of 70%

If you’d like to move forward, we require a deposit of 70% of the estimate.

This reserves your place on our schedule–about three weeks after the deposit is received.

Enjoy new strusture

At this point, all you need to do is sit back and plan for your use of your new structure.

We’ll show up on our agreed date and erect the entire thing in under a day.
