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.

Working with Agra Tech has been a great experience during every stage of the development and construction. Jim Bergantz is dedicated and extremely thorough with a ton of knowledge to bring to the table. We were asked to get several bids on the greenhouses, which only made our decision to work with Agra Tech easier. The others came at it with a ‘one size fits all’ approach, but we had so many things we needed custom done, Agra Tech was a perfect match for us on project.
