Solar Innovations, Inc. began the installation of a cold frame greenhouse today at our corporate facility in Pine Grove, PA. The addition will be attached to the pre-existing Orchid greenhouse and serve as a home for hearty plants during the early spring and late fall months. A cold frames are one of the earliest variations of greenhouses.Generally the cold frame is placed directly above a section of soil that the gardener wishes to grow plants in.Check back in the coming days for finished photos of our cold frame greenhouse, or visit the cold frames page for more information.
