Thanks for that link it motivated me buying an EC meter! I had grown without so far but why not being more precise and know exactly how is the feeding!
This one was the first set i used and i preferred its TDS meter (the ppm reader, the white one)
Water Quality Test Meter Pancellent TDS PH EC Temperature 4 in 1 Set
i preferred it because it has 4x digits so 0000-9999, the other pack (the blue one) only has 3x digits with a 10x blinking symbol that means its in the 4th digit so add a 0.
