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!
GodBud Reviewed by GodBud on . Somebody Please Explain..... I have been reading alot about EC, PPM, TDS meters but still dont quite have a good understanding on which meter would be right for me. I have read that PPM and EC basically read the same thing but you have to use conversion/mathematics. I will have a simple system 4 plants max fed from a 10 gal res. I purchased 3 part nute system from advanced nutrients. Alot of these meters are pricey but they say well worth it. What do you all use to keep your nutrient to volume of water accurate.
