Also on bennies:
I run Recharge - "organic superpack" (myco, trico, bacillus, humic, fulvic, amino + molasses as feed) - in coco dtw with dry salts and very happy with root vigor and health. It is basically a soil amendment product, so I don't expect it would run well in full hydro.
I honestly don't think you can round up this range and quality of micros for less money and for less effort. I pay $50 for a tub that lasts me several months, with twice weekly applications.
I bubble it for 30-60mins only to get it going (it foams like crazy) but it does not need a full brew as with tea. No mess, no stink.
Also at transplant I scratch a tsp of Bioag Vam mycos into the medium, which colonizes upon contact with roots, however I have heard these don't play so well once tricoderma are introduced by the Recharge later. Can't attest to this myself as i'm still learning on this one.
My only other additive is Hydroguard start to finish.
I am currently trialling Mammoth P in this "tea", but have no comment on it at this stage.
