So I have about 40 5 gallon pots full of coco that im wanting to reuse. I’ve always just shook it out, picked all the roots out and reused. But this run is the 2nd (and last) time reusing this set of coco. So I’m wanting to do an actual rinse/wash to prep it and clean it to run again. What’s the best way to do this? Just pure hot water and let it soak or what?
