You are 100% correct and I noticed that I was wrong after I replied, my bad:smokin: I appreciate the suggestion for the PH meter you are refering to. It is very nice and seems pretty reasonable. I do plan on doing hydro with one plant in my next grow, so I would like something worth having. I would like to hear from others too befor I make a decision, I'm suprised nobody else has said anything about what they use.
