A message from banditodan
Somebody just sent me a message about my post about the biochar kiln, and to be fair I wasn't clear so just to clear things up: Don't ever burn anything inside a USED paint can or anything that has had chemicals inside it. You can get new paint cans that have never had anything in them from Home Depot or wherever (I got mine from there). I thought that was kind of obvious, but it was my bad for leaving that out.
Thanks for sharing!
