Nice! My compost worms love being in biochar, great way to get it charged up. Just have a 30 gallon garbage can with holes in the top and a pipe down the middle for extra air.

Very nice. I wonder if they eat any of it.
I have been working it in my chicken bedding a couple times a week. This eventually gets composted.
I also use some in my potting soil after a quick 'charge' in liquid kelp.
