[compost_tea] Re: organic??
At the risk of bring up a topic that has been covered before I joined
the group, I'd be interested in your (and others) opinion as to the
relative merits of compost vs. vermicast aerobic teas. Having use
compost tea for several years, last year I switched to a vermicompost
inoculum, mostly as it provided a high titre starting material that
allowed for fermentations with little or no lag time. Spot testing a
couple of batches on single plantings, it appeared the result were
more dramatic than previous treatment with ACT. Now that I have my
process under control, I will attempt some controlled side-by-side
experiments. In the mean time, what do you folks think?

P.S. If molasses is a no-no, are there any organic alternatives for
those of us the prefer fermenting to ultrahigh microbial densities
