Ventilation

Even in mild climates, your greenhouse will need ventilation. The affordable, low-tech manual side roll-up systems work by allowing you to roll up the long sides of your greenhouse and allow fresh air to roll through.

If you want more control in your environment, then powered fans and fresh-air intakes are the choice for you.

Many customers get both, but typically one or the other is fine.

None $0.00 No additional ventilation package.

Manual Side Roll-Up Ventilation Kit Each kit comes with (2) geared roll-up handles capable of rolling up 300', enough roll-up pipe for each side, billow strapping to hold your system down in the wind, and EZ strapping clips.

Powered Fans Our fans help regulate temperature, humidity, and air circulation, creating optimal conditions for plant growth. They run off of normal 110 plug-ins.

Fan size

Fresh Air Intakes Non-powered vents installed opposite your exhaust fan allow cooler, fresh air into the greenhouse. Unless you have a manual side roll-up system, your powered fans will need them.

Metal End-Wall Kit Package

Add galvanized metal framing kits for both the front and back ends of your greenhouse.

None $0.00 No metal end-wall framing package.

Metal End Wall Kit Our easy-to-install, bolt-together end-wall kits have two major advantages compared with building wood ends: they last longer and are much faster to install. You will typically save about a day of installation time.

Product overview

Peaked-roof strength with room to grow.

The Sunbow Gothic High Tunnel combines a peaked Gothic-arch profile with heavy-duty American-made galvanized steel. Its shape sheds rain and snow more effectively than a standard rounded hoop while providing excellent center height and dependable performance in wind and harsh weather.

Greenhouse kit includes: 16-gauge galvanized steel hoops spaced every 5 feet; three rows of 1⅜-inch purlins; all connectors required for assembly; a complete wiggle-wire system for securing the covering; and 6 mil UV greenhouse plastic with a 4-year warranty.

The extra interior height creates an open, practical growing space for trellised crops, work tables and small equipment. Choose the width and length that fit your site, then add the ventilation and end-wall options that suit your climate and the way you grow.

Available widths: 10′, 15′, 20′, 25′ and 30′.
