GrowSpan Creates an Economical Solution for Cannabis Growers with Over-the-Top Blackout System

The new Over-the-Top Blackout System features a simplified design and economical price tag.

GrowSpan Greenhouse Structures announced the newest addition to their extensive line of greenhouses and growing solutions with the Over-the-Top Blackout System. This is the perfect automated light deprivation system for cannabis growers in need of an economical solution, offering a simplified design and streamlined alternative to complex, expensive interior blackouts.

The system's simplified design allows growers to save money while experiencing the same reliability as a traditional light deprivation system. Users will find the Over-the-Top Blackout is easy to operate due to the two-arm technology and motorized control.

Cannabis growers will enjoy complete control over their crop flowering cycle with the new Over-the-Top Blackout System. With fully automated operation, greenhouses will transform to blackout conditions due to the nontransparent cover made of ultra-durable polyethylene. The opaque fabric is specially designed to prevent sunlight from finding its way inside the structure through gaps, which could throw off cannabis growth cycles.

The Over-the-Top Blackout features an innovative two-arm mechanism to attach the system to the greenhouse and operate efficiently. The arms begin at the peak of the structure with the blackout curtain rolled up, allowing sunlight into the greenhouse. As the arms descend from the top on either side, the blackout curtain simultaneously unravels to cover the structure with the curtain.

The Over-the-Top Blackout System is designed to integrate seamlessly into the GrowSpan Series 500 Greenhouse. The system is readily available in a number of sizes, and GrowSpan specialists can customize the blackout system to fit other greenhouse models upon request.
