So the shipping for Bio-Char that I found (only one company called Arbico) is kinda steep for a 40 lb. bag, but an organic forum talks about techs for making your own or some say you can use LUMP charcoal, but NOT the briquettes, and one guy added,
"You can buy lump charcoal and use it. but piss on it first or soak it in manure tea or even add some urea to it. Adding a high N manure to the char will neutralize the PH, you may want to add other anion containing materials too.
If making your own char you can add some extra ashes which may reduce the production of lighter polymers which are more harmful. By adding ashes you may reduce the polarization frequency and also get a product with less sulfur content."
Yeah, couldn't make heads or tails out of that second paragraph, lol, but I sure can get some lump charcoal and piss on it
. As much as I've been getting up at night to pee, maybe just leave a bucket of it by the toilet, lol, but if I do I probably shouldn't tell my friends/clients about the new "secret" ingredient.... or at least wait until they've been smoking it for a while, then spring it on them
