Would someone please remind me -- I don't remember the thread-- where
an alternative to Perlite was suggested.
I have to shop for a soil "lightening"element, and there was a reason
given why the alternative was better.
If it was about breathing the dust, probably all of perlite, vermiculite &
peat are bad (I think I read peat can contain a fungus). Don your dust mask
& wet whatever you use thoroughly first.
