Well, maybe you got me there, Herbus Maximus is what i call my favorite plants!...I was suggesting how to clean the medium not remove salt...my mistake. I don't recall your "solution to the problem"?
I'll Bite; What do you think of Baking the Hydroton? Several people have spread that method around; Also.

On the topic of salt build-up...I don't think he ever had that problem to begin with...I think he had too strong a nute solution! Period.

Now, I may not be a Chemist or A highly knowledgable horticulturist, but I can grow the 'Hell' out of this plant...big yield, gooey and sticky...and I have used my Hydroton cleaned with a Bleach solution for 4 grows, so far. With no problem. That is all I am saying. later. I gotta go.lw
