I like this post you did, in some weeks to come I will need this info that comes from it. I am glad to hear you can reuse hydroton, my hydro store told me I should not reuse it. Guess they want repeat buisness

My question is keylime says he soaks them in a little bleach? How does not the bleach stay/soak into the hydroton and screw up plants later when you reuse? The rinsing gets out all the bleach out of the hydroton? Not busting balls, just asking the question.
