I have checked my ph tester and its "spot on" as the british would say. PC I also disinfect my entire system everytime I put a new plant in it. I run really large amounts of h202 for several days everytime I start a new grow.

It's gotten to be about 3 times a day now....ppms up to450 and it doesn't seem to have much effect. I'll definitely try soaking them overnight next time and the Flora Kleen idea doesn't sound bad either :thumbsup:
