Sounds interesting
This article on the subject pretty much answers all your questions: https://cdn.intechopen.com/pdfs/67529.pdf

Hardwood lump charcoal is what you want for a biochar input. Many charcoals are manmade with nasty fillers to help them inginite. Hardwood lump is just wood that's been burned/smoldered. Au naturel . I'll put the brand "Cowboy Charcoal" in my compost pile from time to time.

What percentage of your soil mix are you guys adding biochar? I've read 5% is helpful, but more than that and you might run into PH issues, seeing as how biochar can be extremely high PH depending on....factors. I'm just trying to decide whether or not to reduce my soil buffers to account for my bio char's PH. Also, does anyone know if "charging" the biochar with something like fish emulsion has a significant impact on it's PH in the long term?
Your plants themselves actually regulate pH in their rhizosphere as long as it isn't too extreme off target. I personally think biochar is overrated. Bacteria inducing the formation of more stable organic complex compounds is perhaps more beneficial than trying to increase CEC via biochar. But I know that many folks are into quick-fix solutions and don't have the patience to build soil. That's fine too I guess.
