Reusing soil and soilless mediums are fine but you get better results by resetting, sterilizing and re-buffer the medium to get it back to its original state before re-use
Do you have a source for this (for soil)? I have a source that says almost the exact opposite. I would like to take a look at the reasoning and justification behind sterilizing soil. I understand resetting and re-buffering, I do both, but sterilizing is something I typically avoid at all costs, unless it’s through accelerated decomposition.
