I've been growing some time now with rockwool and my next grow I endend to switch to hydroton. I know that first time you need to wash it with h2o to remove dust and so forth. My question is once I have my first grow I know one should " steralize" or clean before reusing. I've heard you can use bleech or hydrogen paroxide, but they never give the delution, can you help?
