https://youtu.be/1c32M99AIaoI am actually sort of pissed of by this video. He hasnt ever talked in depth about soil tests or chemical makeups of soil, at least no insofar as I can see, if anyone can call me wrong people do. He has said in lot of videos that adding sugar to soil is pointless, now when he has a product it is good? I really disliked this video and I swear by this guy.
