I’m sorry that happened to you, Tommy_McCain. You’re the first report I’ve heard of the compaction of rice hulls into concrete, anywhere, ever. Not to minimize your valuable experience, but are you sure it wasn’t due to something else in the worm bin? Do you have any pics or video of the consistency of it and perhaps a log of what you fed the worms that round?
Has anyone else anywhere experienced the same thing and positively linked it to the rice hulls, or is it just your anecdote? I ask because it’s so contrary to everything I’ve experienced and contrary to every use of it I’ve ever seen, heard, or read about.
Regarding using rice hulls for notill growing, every resource I’ve ever read, ever, recommends rice hulls as the only aeration or in conjunction with another type of aeration. They even reference specifically avoiding the soil compaction scenario you’re talking about. Here’s a few:

You’d think if it routinely turned into concrete, none of these pros and soil scientists would recommend using it to do the opposite in soils and composts. That’s why I asked - it doesn’t make sense at all. Why would they steer all of us so obviously wrong if it even has a slight chance of doing what you said? It’s not like the retailers make much profit on this stuff. lol They could make a lot more just by selling us lava rocks and biochar.
Sorry, I thought you were synthetic because you commented about using Promix in this Hempy pot using Promix HP? - #9 by Tommy_McCain thread. Don’t get a lot of organic growers using Promix since the same thing can be had for about 1/3 the price if you just buy peat.
