Hi, How do you all clean/sanitize your clay aggregate? I went to a hydroponic website that said "Reuse over and over by rinsing out roots then sterilizing in a very mild bleach solution". What dilution is considered "very mild", 10:1? Is this what you all do? Since it is fired clay, could you not put it in the oven to sanitize it? Is there a maximum number of times you can reuse it? Thank you all for your help, jrbl
