Skunkface said:Greensand is great stuff. It VERY slowly releases potassium (k), and provides tons of rare minerals and silicas. you can use lots of it.. 5% of ur soil mix wouldnt be a problem, you can use even more, but its expensive.
As for the guy that said green sand is a scam, and the other guy who said "Green sand is very small grained.. it makes small cuts in the roots so micro roots can form quicker." you guys obviously have never used greensand and dont know what its all about. plz let people with knowledge talk.
