biochar. possible beneficial for growing?

Hey yall I am not sure if this is right place to post but mods will take care of it anyway! bless them. anyways! i came across this article and read about it. it gave me an idea! I thought that biochar can be applied to growing a healthy marijuana plant since biochar does not release CO2 to atmosphere and roots can absorb CO2 in order to facilitate the photosynthesis...what do you think dude and dudettes!!!????
p.s. I am hoping that biochar will go to consumers
