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.
“The team at Agra Tech met the challenge and did a great job from start to finish,” Thomson said. “The completed house system is state of the art with fully integrated & automated controls for all operational aspects; fan speeds, lighting, cooling system, shade curtains and includes a PC based program interface that provides for monitoring system performance and set up. When small build issues arose, as they will, the Agra team stepped up and responded quickly to resolve the challenge. The new greenhouse represents a significant jump forward for Lundberg Family Farms not only in the overall system but also in the Head House space that was custom created for our own team. Agra Tech and Ag-Con worked in conjunction with our General Contractor to tie in a custom head house built by our general with a state of the art Green House, they did an excellent job.
