Oboy. I'm trying to make Desert Roses happy. The Taiwanese nursery man that I'm buying from uses "Carbonized rice hulls" Could you discuss charcoal, briefly? I remember a high school experiment that we put chunks of wood in a tightly closed can that had a pinhole in the top, and when left on the Bunson Burner for hours, it steamed. Then finally, we opened the can and had charcoal.

I figure this is what they do to make carbonized rice hulls.

Thanks in advance.

Hi, Melissa -
I don't know a lot about the product specifically, but I do know that hort charcoal in container media is about the equivalent of perlite, as far as it's function. It doesn't sweeten the soil or absorb salts or other 'impurities; nor does it filter anything from the soil or act as a disease suppressant. If you choose it as a soil component, I would choose it like any other - based on its size and longevity in the media.

Hum, OK. I have enough coconuts around that I'll do as Esteban says, and run the car over them to squash them and break them up a little. I'll post once I do this... haha
