I don't hang much in the Organics forum, but I do remember being told that most potting mixes already have beneficial bacteria, and the idea is to keep them alive and healthy. No need for additional beneficials, if you are caring for those already there.

Be very wary of marketing tactics. Especially in the marketed organics world where blind faith is freaky-rampant. They are trying to convince you of the need for thier miracle crap. Just like Superthrive, vitamin B, transplanting shock liquids...all garbage. And use care with organic teas...they are a great place to breed e-coli and the like.
