Patented Automated Light Deprivation A TRUE BLACKOUT SYSTEM

Why Light Deprivation?

Whether it’s pulling tarps or utilizing cutting-edge automated curtain systems, the benefits of light deprivation (or light dep) cultivation are undeniable: it can increase harvests from one outdoor grow to at least four or five a year, it significantly cuts energy consumption and total cost of operation compared to indoor cultivation, and it’s ultimately more sustainable. Automated light deprivation greenhouses now leverage enough technology and equipment developed for indoor grow rooms (supplemental lights, ventilation, environmental controls, dehumidifiers, etc.) and use them to complement or augment the effects of outdoor growing. This allows light dep greenhouse growers to maintain optimal temperature, humidity, lighting, and the ability to guard against pests and mold to have a totally controlled environment.



Our system is not an afterthought or a product purchased from another manufacturer. It was specifically engineered in conjunction with our Sierra and Alpine Series greenhouses to promote easy assembly and functionality without sacrificing quality or design.

The patented automated system opens and closes a 3-layer, breathable blackout fabric within minutes. Using only premium grade materials including galvanized 2” x 2” square steel tubing for increased stability and marine grade lubricants, we ensure the proper functioning and complete blackout of our systems. The square tubing provides two flat surfaces to marry and create a true blackout system without the use of flimsy rubber gaskets. That, combined with our 4-corner roller assembly, fixed and leading edge (c-channel), and no-snag gutter system make our automated light deprivation system the best investment for your harvests and your business.

We have spared no expense in designing and manufacturing our systems so you, the grower, can have more time and confidence to harvest and prosper.



Four corner roller assembly

Our unique roller assembly is installed in all four corners for even weight distribution. When the system is opened or closed, the weight is evenly distributed to reduce friction and wear on the breathable blackout material.

C-Channel and fixed edge closure system

We designed a square tubing and C-channel closure system to provide a gasket-free, light tight seal. Most systems use aluminum extrusions and gaskets. Aluminum extrusions are weak and flimsy while gaskets are a maintenance issue. With our system, these issues are eliminated.

No Snag Gutter System

As opposed to the common use of ground cloth for the bottom of the curtain, we developed a snag-free metal gutter system. Our system has a supportive purlin along the length of the gutter to make it completely rigid which ensures smooth opening and closure of the curtain.
