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.

It has worked out well for all of us and it’s a great relationship. Of the 274 greenhouses we have, all but 19 of them are from Agra Tech. Jim Bergantz, our rep from Agra Tech sells them to us; John Pound advises us: Anita Pound helps to engineer the structures and Ray Pound’s company Ag-Con in San Jose, CA does all of the construction. The people at Agra Tech are easy to work with and every time we’ve gone to them with requests, design modifications and things like that—they’re always willing to make it happen for us.
