Is 20kg of medium size 4mm vermiculite the same as 200 litres please?
Found 20th Mar 2015
I ordered 200 litres of medium size vermiculite and was delivered 20kg instead. Meanwhile, i also received 200 litres of perlite and was delivered exactly that. The perlite sack is much bigger but lighter. Apparently, it requires density to help with conversion. Can any mathematician help please? I feel like complaining...
