The first time i tried my newly built awesome dwc closet set up after the phemonimal yield in a cheap tupperware I attempted it with low ppms about 700 or 1.0 ec and got the horrible results i am speaking of an d now seeing duplicated. Right now in the ebb and flow I have lowered it to an EC of 1.5 or 1300 ppms i am using a hanna 8913 meter and it has a wierd conversion of 739 whenever i do the math, I have two of these meters they both do the same thing. Anywho i think they can handle a wide range of ppms and yield great though there is an optimal number. I think the less you flood and drain the lower you must go. When i used to water this same strain in pro mix every other day in peak flower they were exploding with 1800-2000ppm on this meter for years! I am down to 1300 ppm now in the ebb and flow watering once a day i dare not go lower right now.
