Coco with biochar in place of perlite or growstones?

Anyone using biochar in their coco in place of perlite and/or growstones?

If so can you tell me the ratio you’re using and how you like it?

Are you having any pH issues (depending on biochar feedstock)?

I’ve read a lot of articles and seen the database from Davis - just looking for some live grower feedback though.

Thanks.
