After seven years of trying to grow a garden and failing, I decided to have my soil tested. The test result showed that I have really high PH and above critical levels of Sulfur and Calcium. A friend of mine that is crop insurance adjuster and some what of an agricultural expert suggested that I should use Reverse Osmosis water to irrigate my garden with (I have a trip tape system). I am wondering there is special Reverse Osmosis system for use with gardens. Any Advice?
