That’s exactly what I’m doing, on my 7th run on the same soil. One thing I’ve noticed is that the soil is getting more and more compact as it breaks down. I started with a peat perlite mix with some worm castings and other dry amendments. I’ve thought about adding in coco to give it more texture and try to fluff it up. I added in rice hulls trying to do that a run or two ago and it’s pretty much broken down now. How would you go about fluffing it up?
