Chemical potentially causing damage to greenhouse tubular/metal components
Our primary supplier of tubular steel has issued a warning about the use of Copper Sulfate to treat algae on greenhouse floors.
Copper Sulfate is produced by dissolving copper in sulfuric acid. The resultant metallic salt (copper sulfates) ions will oxidize the iron and zinc to rust and reduce itself to copper metal. The copper will try and selectively destroy metal surfaces over 50 times faster than common agricultural chemicals such as potash, ammonia or phosphates.
Please ask that you discontinue the use of copper sulfate in your greenhouse.
Agra Tech uses the finest quality tubular steel with acrylic coating for maximum protection. Greenhouse purchasers should be aware that some other greenhouse suppliers are not meeting NGMA standards for coated steel.

Sunridge Nurseries is excited to announce that it has embarked on an expansion project that will increase their overall production area by an additional 7 acres of greenhouses and shade houses. These state of the art, Agra-Tech solar light ranges will come equipped with the latest technologies in greenhouse climate and irrigation controls. By incorporating higher gutter heights, ridge roof vents and internal shade curtains, coupled with energy efficient double wall polycarbonate coverings, we expect to shorten our crop time on potted grafted vines and do it with fewer energy inputs. Other features include the addition of HAF fans and light diffusion in the polycarbonate coverings which will allows us to grow at higher crop densities without sacrificing plant quality.
The expansion project will increase our overall capacity by 2 million potted vines under a protected insect free environment. This, along with all concrete flooring and roadways throughout the entire project and our continued use of all metal benching, will help to provide for a more disease free growing area. The ability to wash down benches, floors and walkways with disinfectants both before and after vines move thru the facility is a critical step in keeping the vines free of unwanted diseases.
