Gutter Connected Greenhouses Description
Gutter connected greenhouses like the Luminosa are an excellent choice, designed to optimize crop production while providing a durable and reliable growing space that stands the test of time.
These gutter connected greenhouses is ideal for high-density, commercial multi-crop production due to its large, modular structure and efficient environmental control. With bay widths ranging from 21’4″ (3,7m) to 36′ (16,2m), the Luminosa maximizes usable growing areas, boosting crop development and operational efficiency.
Crafted from certified structural steel with a minimum strength of 50 ksi, the Luminosa is 52% stronger than standard commercial steel tubing. Its oval design minimizes wear on polyethylene films, extending their lifespan and ensuring a durable, long-lasting environment.
These gutter connected greenhouses maximize crop growing space with an under-gutter height of 12 to 20 feet.
It offers multiple ventilation options, including single or double ridge vent panels, mid-roof vents, side roll-up vents (manual or automated), and mechanical ventilation systems (fans, extractors, and air circulators). These features provide superior natural ventilation and effectively reduce water, ice, and snow buildup, creating an optimal growing environment for all seasons.
