Hey Harvester, I got the GSE powder on Amazon, and I used , as Smot says above, 1 tsp per gallon. After I could see that the rot wasn't coming back, I used it with my nutes. I did a couple of days just GSE in pHed water at first (after I had gone the H2O2 route to no avail). I had such a bad case last time, that I had to take the girls out of the reservoir, one by one, and spray them at the kitchen sink, gently moving the roots around with my fingers to get all the gunk off of them. And there were the white roots underneath all the gunk.
