I use Vegamatrix. It's not "100%" organic because there a couple percent of stabilizers there because it's a shelf stable product. It's nothing crazy that I really worry about. The big selling point is for those who use it legit as medicine because products grown with vegamatrix (or veganic in general) test in the parts per billion when it comes to heavy metals and that's important for patients. it will ALWAYS be better to cook your own nutes, but for those of us who got other shit going on I do like pre-bottled veganic nutrients.
