Bringing up pH levels in your aquaponic system with Bright Agrotech's Nate Storey. https://twitter.com/BrightAgrotech http://www.facebook.com/BrightAgrotech https://plus.google.com/101481681830976288924/posts Bright Agrotech manufactures vertical growth towers for hydroponic and aquaponic crop production. Our towers can be easily integrated into existing HP or AP systems with minimal fabrication and increase yeilds 2-3 times. (In some cases much more!) We are also currently testing a market display which incorporates the towers directly, allowing consumers to cut live produce! Find out more at: http://www.brightagrotech.com
