30'x100' Auto Ventilated Quonset Greenhouse w/ Heater + Twinwall Ends

This package contains 8mm twin wall sheets, aluminum extrusions and the required hardware to sheath the greenhouse end walls. Twin wall poly carbonate has a 15 year manufacturers warranty against yellowing.

Modine has become the industry standard in forced hot air heaters. The PTP series is an exceptional greenhouse heater that blows dry air. Covered by a 2 year manufacturers warranty, must be installed by a licensed plumber.

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.

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.

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.

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.

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.

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.

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

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.

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.
