"CT Greenhouse was awesome to work with. The high tunnel materials are top quality, the instruction book was one of the best I have seen for any product. Tobby and Aaron were always ready to answer any question I had during the build and getting my order ready. A pleasure working with farmers that understand farmers needs."

Description
The Grower Pro Series High Tunnel is our fully loaded high tunnel kit, built for commercial growers and market farmers who want every premium feature from day one. This double-layer high tunnel kit is built on 1.9-inch, 13-gauge American-made galvanized steel tubing and ships with twin-wall polycarbonate end walls, 8' × 7' double sliding doors on both ends, woven roll-up sides rated for 7 years of UV exposure, a steel and polycarbonate baseboard system, and a trellis cable system. Every Pro tunnel is designed to meet USDA NRCS Conservation Practice Standard 325 (CPS 325), the standard used for High Tunnel System funding under EQIP.
What sets this kit apart is that features which are usually separate purchases come built in. The 8mm twin-wall polycarbonate end walls insulate better than poly film and hold up for years without re-covering. The double sliding doors stay on track in wind and snow, giving you full equipment access from both ends. The woven roll-up side material is separate from the top cover, so you can install the sides on a different day, even in wind, and at re-covering time you replace only the top plastic without rebuilding the roll-ups. The steel and polycarbonate baseboard system removes the need for locally sourced lumber and the maintenance that comes with wood on the ground.
The Pro is available in widths from 14 to 34 feet and any length to match your crop plan and site, with a choice of standard (5') or tall (6') sidewalls. A 30-foot-wide tunnel is a popular starting point for the working room it provides. Because NRCS contracts are sized to your operation and cost-share rates vary by state, your local NRCS office can confirm the size and funding that fit your project. CT Greenhouse provides the engineering specifications and manufacturer certificates your local office typically requires.

If you're building an NRCS high tunnel and want everything included from day one, the Grower Pro Series is the pro high tunnel kit that gets you there. It's built on the same commercial-grade 1.9" 13-gauge American-made tubing as every CT Greenhouse structure, with every premium feature ready out of the box: twin-wall polycarbonate end walls, 8' × 7' double sliding doors on each end, a double-inflated layer of 6-mil greenhouse plastic, woven roll-up sides rated for 7 years of UV exposure, a steel and polycarbonate baseboard system, and a built-in trellis cable system. No add-ons to buy. No lumber to source. No upgrades needed down the road.
Available in widths from 14 to 34 feet, any length you need (commonly 48, 72, or 96 feet), and your choice of standard (5') or tall (6') sidewalls. Every Pro kit is designed to meet USDA NRCS Conservation Practice Standard 325 (CPS 325). Contact us for a custom quote or call 860-341-8707.

What's in the Grower Pro Kit
| ✓ | 1.9" 13-gauge galvanized steel main bows (commercial-grade American-made tubing built to handle wind and snow loads, a heavier gauge than most high tunnel kits in this category) |
| ✓ | 1-3/8" 16-gauge tubing for trusses, purlins, and roll-up pipe (provides lateral strength and supports the roll-up side mechanism) |
| ✓ | Galvanized steel-framed end walls (built to carry the twin-wall polycarbonate panels and the sliding doors on both ends) |
| ✓ | Double layer of 6-mil, 4-year greenhouse plastic (double-inflated for better insulation and more consistent growing temperatures throughout the season) |
| ✓ | Twin-wall polycarbonate end wall covering (8mm polycarbonate panels on both end walls for better insulation and a long service life with no re-covering needed) |
| ✓ | Woven roll-up sides rated for 7 years of UV exposure (woven polyethylene that resists tearing during daily operation. It's a separate material from the top cover, so you can install roll-ups on a different day, even in windy conditions) |
| ✓ | Wind exclusion panels and bug netting under roll-up sides (reduces pest entry and cold air infiltration at the side gaps, so you get airflow without the insects) |
| ✓ | Aluminum double wirelock hip board (secures your plastic film at the base of the bows for a tight, lasting seal) |
| ✓ | 8' × 7' double sliding doors (two 4' × 7' doors per end) (sliding doors need no clearance arc, open fully regardless of wind conditions, and provide wide access for wheelbarrows, carts, and equipment from both ends) |
| ✓ | End wall peak vents with automatic opener (temperature-activated vents that open on warm days and close when it cools, no electricity or manual adjustment needed) |
| ✓ | 5:1 gear crank roll-up side operators (5:1 gear ratio for smooth sidewall operation, so you open and close ventilation on both sides with minimal effort) |
| ✓ | Steel and polycarbonate baseboard system (no lumber to source locally, which removes the maintenance cycle of wood baseboards) |
| ✓ | Trellis cables and support bracing (ready for tomatoes, cucumbers, or any crop that climbs) |
| ✓ | Grade 5 bolts and stainless steel self-tapping screws (corrosion-resistant hardware throughout) |
| ✓ | Aluminum fabric clips for roll-up sides |

What Makes the Pro Different
Twin-wall polycarbonate end walls
The Pro's 8mm twin-wall polycarbonate end wall panels provide better insulation than poly film and hold up for years without re-covering. The trapped air channel in the twin-wall construction acts as a natural insulator, keeping heat in during cold nights and reducing temperature swings. Many typical high tunnel kits ship with poly film end walls or offer polycarbonate as an add-on upgrade, while the Pro includes it on both ends from the start.
8' × 7' double sliding doors on both ends
Sliding doors stay on their track in wind and snow and need no clearance arc, so they open fully from both ends and let you drive a wheelbarrow, garden cart, or small equipment attachment straight through. Each end has two 4' × 7' doors that slide open to create a full 8-foot-wide opening. Typical high tunnel designs either omit doors or offer them as a separate accessory.
Woven roll-up sides rated for 7 years of UV exposure
The Pro's woven polyethylene roll-up sides are made from a heavier, woven material that resists tearing during daily rolling and holds up to contact with irrigation equipment, trellising hardware, and tools. Because the roll-up side material is separate from the top cover, you can install the sides on a different day, even in windy conditions. Aaron's note from the field: separate roll-up material is the real money-saver, since re-covering the tunnel down the road needs only a smaller roll of plastic and you don't have to take the roll-ups apart and rebuild them.
Steel and polycarbonate baseboards, no lumber to source or replace
Standard high tunnel designs use wooden baseboards, typically 2x10 lumber that you source locally. That lumber sits on the ground, in contact with moisture, and eventually needs replacement. The Pro's galvanized steel and polycarbonate baseboard system removes that maintenance cycle. No lumber to buy, no lumber to replace. Like the rest of the frame, it's built with American-made tubing for corrosion resistance and long-term durability.
Trellis cables and support bracing for vine crop production
If you're growing tomatoes, cucumbers, peppers, or any vine crop, you need a trellis system. Most typical kits require you to purchase trellis cables and hardware separately. The Pro ships with trellis cables and support bracing built into the frame design, ready for vine crop production from the first season.
