I have used oakton meters for yrs,and im very pleased.Yea without a meter you really dont know if there using more of the h2o,are the nutes.And too really push a plant a meter is a must and after you learn the strain,like my AK47 is a very aggressive feeder and can handle alot of nutes.just got TDS meter in the mail, sweet!!!!!. Now i can really tell how much water/nutrients my plant are using. And how concentrated the resevour is
