Looking back that was kinda jumbled post on my part wasnt it.
I learned alot from this post by seamaiden......
If your goal is to culture microbes, that site is exactly what you need. Microbeman has done the most work on this stuff (aerated compost tea, or actively aerated compost tea) and his work is cited all *over* the place, including by many (organic production) professionals. If your goal is to do it right for the least cost, again, that site is what you need. I believe that we've discussed using other sugars and he has relayed that he hasn't tried making teas with anything other than molasses. However, there's a group of people who are playing around with sprouting different grains and seeds, including BARLEY. And I capitalize this because for quite a few years now I've been using leftover malted barley extract, both in teas and feeds, to some very nice results.
Look up secondary plant metabolites, and you'll begin to understand why the sprout teas, and why malted barley might be helpful in cultivation. ;)
I do recommend that teas include a small dose of micronutrients. Their necessity as cofactors for bacterial enzymes cannot be overstated.
I'd actually defer to Microbeman on that one, he's got the scope time & experience to really discuss responses, on a group by group basis. E.G. he no longer recommends using kelp in teas, as he's found it actually does not help boost any populations--bacteria, protozoa, or fungi--that we're after in this context. However, it certainly adds to the nutrient profile, irrespective of whether or not it helps us culture microorganisms. As would adding micros in whatever form; E.G. Azomite, bentonite, kaolin clay, volcanic rock dusts, or a liquid.
Back to the OP and subject at hand;
Now, if your goal is to feed nutrients, that can also be achieved via ACT, but I personally feel that some care should be taken when using some ingredients for teas, mostly manures from vertebrates. This stance comes from food handling experience/mindset and really nothing else.
Just remember that the worm castings are your inoculant and source of some nutrients, and the sugar feeds bacteria.
Can these methods be applied to coco?
