Thats kewl I will invest in the meter and the up/down solution. Just out of curiosity do you apply the up/down?
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.
