Word of caution. Moisten it before use. Glass fibers in the lungs last forever.

One other issue I have with it, is that it loves to grow moss in my clear pots. Other than that, I really like it. I have yet to use it on anything other than phrags. What plants were you going to use it on?

My paphs and phrags do very well for me in semi-hydroponic culture using LECA, so I won’t be messing with that. I grow my phals in sphagnum, so they seem to be likely candidates, but I have a couple of bollea/warczewiczella/pescatorea intergenerics (also currently in moss) that might be the first choice.

I’m not too concerned about the handling. I’m a ceramic engineer who has worked with all sorts of glass, powder & chemical manufacturing, including radioactive powders since grad school, so I’m pretty well trained in safe handling.
