Standard Features:

This kit includes all of the following parts and systems

J&D Exhaust Fan

Exhaust fans are sized to evacuate the full volume of greenhouse air within one minute to prevent the greenhouse from getting hotter than the ambient outside temperature. At night, these units are great options for controlling humidity.

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.

CUSTOMIZATION

Choose your length, truss spacing, sidewall height, and equipment

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.

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.

Galvanized Steel End Walls

We use 2” square tubing for our end wall framing kits. The kit includes the uprights and horizontal wall pieces required for supports and rough openings, and installation hardware such as brackets and screws.

9 mil Woven Greenhouse Plastic

Our 9mil woven clear greenhouse covering has an anti condensate coating and a 87% light transmission. This heavy duty poly has a lifespan of 5-8 years depending on the site conditions.

5’x6’ Sliding Door

Sliding doors are more resilient to wind than swinging doors. Door kits come with trolley rail, door hangers, door handle, stay roller, and door catch. Note that the cover is not included.

J&D Power Intake Shutter

Aluminum intake shutters automatically open when exhaust fans turn on to allow fresh air into the greenhouse.

J&D Circulatory HAF Fans

Horizontal air flow fans greatly improve plant transpiration by stirring the air. Reduces heating cost by distributing air evenly throughout the greenhouse. Increased air flow strengthens plants and grows thicker stems to support larger fruits.

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.

No LUMBER or CONCRETE provided with greenhouse kits
