Rainbow® Plus

Durable greenhouses for dependable crop protection.

The Rainbow® Plus sets the industry standard for quality, performance and value. This greenhouse gives growers a strong and durable house with the capability to cover anything from 1,000 to 1 million square feet. Available in Rainbow (rounded-arch) or Diamond (peaked-arch) profiles, the low-profile roof line reduces heated surface area and stratifies the air, while increasing summer cooling efficiency.

The Rainbow® Plus is a versatile and affordable choice for any grower, from commercial growers who require a spacious and flexible growing space with maximum environmental control, to smaller start-up operations looking to get rooted with a smart, reliable structure. Construction is simple and easy because of built-in connections for columns, bows, horizontal bottom members (HBM) and eves. Y and L connectors are hot-dipped galvanized after fabrication, and direct connection of bows to columns through the connectors accommodates higher loads with open columns, while offering easy connection of the HBM or truss to meet the toughest conditions and codes. The Rainbow® Plus’ all-aluminum gutters are designed to work for water removal rather than as a structural member, while they also have an extruded-in Polylock® that makes coverings installation more efficient.

Rainbow® Plus: Transplant

Offering all the best of the Rainbow® Plus, the Rainbow® Plus: Transplant is designed for growers in need of a greenhouse that makes harvesting efficient and gives enough square footage for seedlings and transplants. By widening the house to a standard 35’, there is more space for plants and watering booms, increasing efficiency. When combined with Stuppy T-rails and drop curtains, every square inch of the greenhouse’s space can be used, with easy harvesting directly from the sidewall. When designed for transplant, the Rainbow® Plus’s versatility allows growers to cover any seedlings, plugs or transplants, from 1,000 to 1 million square feet.
