reply to michaelangelica
bernardo tadeo talked for 15 minutes about rice hull char
Oliver Enterprises
oliver rice mill
is selling carbonized rice husk
this information is old
and may not still be true
another name for rice hull char is kuntan
it has been used in japan for 100 years
what I found in the USA was
PBH growing medium material
it is not char
