Thanks for the input folks. I purchased a HANNA HI991404 GroChek pH/EC/TDS/TEMP Monitor/Meter/Tester. I hope I dont regret it after what Latewood stated but it seems like a pretty good meter and it does it all. I spent about a bone forty on it. Comes with AC power adapter so no messing with batteries a feature I really liked. Also comes with all the calibrating solutions. What the hell I am just gonna roll with it. If it flakes on me and Hanna gives me the dickaround then I will try another brand as Latewood suggested. I called Advanced Nutrients and this dude answered. He was super cool and pretty much knew what I was talking about regarding what I was planning on growing and gave me lots of info. He was in BC Canada. One thing I do have a question about is Hydroton and net pots how in the hell do you keep that medium from falling into the res. I am going with cutting out holes in the lid and letting the roots just grow down into the solution.

Thanks brothas!
