30'x70' Dual Frame Internal Light Deprivation Greenhouse w/ Advanced Controls

Frames are separated to create a 2ft thermal air bubble and protect the light dep system from weather. Our frames have 2 3/8” sidewall posts, 1 7/8” arches, and 1 3/8” purlin. End wall framing is made from 2” square tubing.

A roll to peak light dep is the most economical way to blackout the greenhouse. Putting this system inside the greenhouse protects the system from weather. Easier and less expensive to install compared to a curtain system.

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.

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.

Greenhouse frames can be strengthened with truss reinforcement. These packages can be designed to add reinforcement to every bow or every other bow. This is recommended in areas with high wind or snow.

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.

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.

Light traps are used to block light from entering through intake and exhaust openings when the greenhouse is blacked out. Hortitech light trap housings are made from heavy duty galvanized sheet metal.

These assemblies consist of telescoping arms, swivel brackets and galvanized 2” square tubing. They serve as the anchor and pivot mechanism for the manual or automatic film reelers. These are essential in roll to peak light deprivation systems.

Film reelers are simple mechanisms the spin a roll bar in order to roll up plastic. They can be automatic or manual. Film reelers come standard with adapter for 1 3/8” OD pipe.

The Agrowtek GCX offers modern growers a reliable and flexible system to manage, monitor, and control all aspects of their facility's climate, irrigation, and hydroponics systems. This includes HVAC temperature and humidity control, light dimming and spectrum control, crop steering irrigation, CO2 injection, nutrient dosing, and more.

Custom heavy duty galvanized metal ducting is used to bring in fresh air into the internal grow space. Light traps block light from entering through intake and exhaust openings when the greenhouse is blacked out.

An evaporative cooling system efficiently regulates greenhouse temperature, promoting optimal plant growth. It uses water evaporation to cool the air, providing significant cooling on the hottest days. This system also maintains higher humidity levels, preventing plant stress and ensuring a healthy growing environment.
