Adaptive Plastics, Inc , manufacturer of Solexx greenhouses and greenhouse covering, was first introduced to corrugated polyethylene plastic in 1986 and began manufacturing insulated twin-walled fruit harvesting totes for growers
After experimenting with the corrugated plastic as a hot house covering and seeing how well tomato plants grew under the material, Mike and Bev Perry (CEO's) got the idea to use the panels to design a hobby greenhouse kit. University testing verified that the flutes in the twin wall plastic diffuse the light and capture it from various angles â€“ accelerating the growth of plants. From there, with their backgrounds in biology and plant science, they set out to design an affordable, strong, and practical greenhouse that would be easy to use for all home gardeners â€“ the Solexx Greenhouse.
