Hydoponic-Fallponics Grow System

This week found a controller that I could put in my Reservoir and it gives me a constant TDS/EC PH and Temp right to my phone. It makes a huge difference in knowing exactly where I am at. LIFE SAVER for Hydro. Still without a good chart I had my PH close to what I would have had for this week in soil. Not a good thing, I brought it into comfortable hydro standards of 5.9. Other than that I found that the controller needs to be re-calibrated every 5-7 days because it starts giving slightly higher of lower readings. Day 26 I did my first Official non emergency water change. Ended up with a 780PPM and a 6.01 PH.
