I am a No Till Grower not a synthetic.
I use rice hulls as a mulch because they decompose. I have used them in static worm bins (these sit for 6 months to a year) they break down over a year and my worms die because of a lack of aeration. The worm bins are like concrete. I have also used perlite and not had as many worms die off.
Yes, you can use rice hulls in organic grows where you remix your soil after every grow. But only using rice hulls as aeration can cause issues in a No Till pot over time. My worms and other microbes love to eat rice hulls.
