Meters, Ph Up/Down Solutions

There are three things you have to do once your season is underway: adjust your ph, adjust your TDS (Total Dissolved Solids, or nutrient concentration), and periodically change your reservoir.

Technology makes this simple. You need a meter to monitor your nutrient concentration. And you need either a Ph meter or Ph strips to monitor your nutrient Ph. A TDS meter from HM Digital and 100 Ph strips are included in most system packages. Eventually there is nothing like upgrading to a real Ph Pen and a pocket TDS meter. The very best situation is a Pro Combo TDS/PH/EC meter from Milwaukee Instruments or Hanna Instruments. Check out our selection.
