Never heard that one cullenperry, but have been using it for just over a year with great results. I use 2 capfuls per 2.5 gallons of water along with Jacks fert. I do have to say I don't use bark as a medium for my orchids which does hold its fert and ST inert ingredients. Using aliflor as my choice of medium it does not soak into it's factor as orchid bark does.
When repotting I use ST as a rooting stimulant and my orchids show less signs of stress after placing them in there new home enviroment.
The first bottle of ST I got was from a friend who used it religiously and by looking at the bottle lid, it appeared to have been aged, no issues no problems just great changes urging me to purchase a new and larger bottle. Nope no born on date that I could see.
