Hi,
 Last December I talked to you about how to use Hygrozyme in my aeroponics setup.  At the time I promised to tell you how I made out.

I am very delinquent in informing you that all has gone very well. I properly disposed of the Physan 20 and instead treated the growing medium (expanded-clay balls) with Hygrozyme and add Hygrozyme weekly to the water when I replace it in the aeroponics garden.  I have been producing tomatoes for almost a year now and all seems to be quite good.  No algae anywhere and no visible diseases and the tomatoes continue to set and mature.

 A belated but sincere thanks for your help last year.
