I just have the vinegar in the grow room, in case lol I've never actually had to use it I can usually balance my ingoing Ph with my waters n nutes easy enough, up is really the only thing I need and its really only needed for the recent flushing to try and fix my recent problem, and as far as the drops ya tell me about it!! 8 brands ya!! No joke and that was my first thought but if that were the case all the water I have been testing wouldn't be right and the drops react with my water the way they should dropping with vinegar raising with Ph up its only run off doing this!!??
