Well, I was never directly linked to them. The people on the farm probably still deal with them, but with me leaving the farm about 2 years ago I have lost touch with the rest of the team, just stayed friends with a guy that works there and don't really use big amounts of synthetic fertilizers so don't really go to them if I wanted stuff these days.
Long before all that I did 3 coco grows with synthetic nutes, one half decent one, but then did a run in FF green bag with synthetic nutes and I had pretty good results, but then got that "no synthetics in living soil" lecture so stopped using synthetic stuff. all organic these days
