I am in the reuse camp also but with a twist. I don't reuse what I just grew in for my next run, I put in with compost and let it sit for a run. I don't know your space limitations but if you have an area to let the soil rest, add compost and whatever other ingredients that go into your mix I think you will ove the results. Keep feeding your soil, adding molasses and other food for your microbes to eat and create a soil that is well blended and totally alive for your grow. I have lots of space for my soil and usually my soil gets to sit between one and two years before reuse, but not everyone has the space or dedication to allow for this. Good Luck and Happy Growing
