Greenhouse products

FEATURES

√ Suitable for natural or mechanical ventilation, the SHG Multi-Span Poly Greenhouse has a unique roof vent design which allows for maximum cooling: the bottom rail of the vent opens above the ridge, eliminating trapped hot air. An additional benefit of the raised bottom rail is the ability to easily vent regardless of outdoor conditions.
√ Designed to readily accept hanging baskets, lights, booms, echo systems, and other needed equipment, the truss system can be designed to support each piece of supplementary equipment without additional structural members. This truss has also been designed for use with heat retention and shading systems, minimizing summer heat gain and winter heat loss.
√ With the bowed sidewall, you will benefit from added growing space immediately, while having the necessary components to expand later. Since the optional bowed sidewall utilizes standard components, expansion is easy with the addition of posts and gutter.
√ Available in standard and custom widths and heights to suit your needs. Complete design specifications and structural details are available.
