High Tunnel Features

Galvanized Steel Frame

Our greenhouse frames are made up 2 3/8” sidewall posts, 1 7/8” arches, and 1 3/8” purlin. 2” square tubing is used for end wall framing kits include the uprights and horizontal wall pieces required for supports and rough openings. Hardware such as brackets and screws are included.

6 mil Greenhouse Plastic

6mil plastic is the industry standard cover for cold frames. It comes in multiple varieties such as 1 year, 4 year, and infrared/anti-condensate.

Plastic Fastening System

Wire lock, commonly referred to as “wiggle wire” is the industry standard for attaching greenhouse plastic to the greenhouse. For 6mil plastics use PVC coated wire, for woven plastics use galvanized wire. Hortitech manufactures its own aluminum deep channel base capable of fitting multiple layers of plastic and wiggle wire.

Roll-Up Sides

Roll up side walls are a great way to utilize passive ventilation to cool and dehumidify your greenhouse. They can be powered or manual and include a wind retention system.

Semi-Gable Shape Benefits

The semi-gable frame offers more headroom and growing space compared to quonset shaped designs. Its shape allows for snow shed and more room to add truss reinforcement.

Quonset Shape Benefits

Quonset shaped greenhouses use less materials than semi gable designs and are best used in mild climates with little to no snow load requirements. They have less air volume making ventilation and climate control less expensive.
