Dennis - The SFI report for compost gives the dry
weight of 1 gram of the fresh material so I've always assumed the whole report
was on a dry weight basis. The tea report is in ug/ml so there it is on a dry
weight basis for the microbes also, at least that is how I've always read
it. Sound correct?

tea was analysed and had good numbers for both active and total
bacteria. Active bacteria at 200ppm is only about 0.67 ounces of
bacteria in 25 gals. It's not hard to imagine that 2 oz. of sugar
can grow way more than 0.67 ounces of total bacteria. It goes
something like this for 25 gals of tea: > 25gals x 8.35pounds/gal x
16oz/pound = 3,340 ounces of tea x 0.000200 (200ppm recommended active
bacteria) = 0.668oz.

Dave, So using the above calculation(example) the bacteria are
weighed. Is that right? 200ppm active bacteria in 25 gallons
water weigh 0.67 oz. Would they be dried or as is, basis?
That's interesting. Dennis
I'm not sure why the
basic recipe in the Compost Tea Brewing Manual calls for 16 ounces of
molasses/50 gal brew. It will certainly grow a lot of bacteia at
just 0.2 percent of 50 gals. I understand that the 5% rate is meant
to actually inhibit the bacteria for a fungal brew. > >

isn't that like 0,06% molasses? that would be far from the 5% I recall
reading as a max. here in this forum... >

> Alex - Maybe there are paint filters with different size
holes? I can filter five gallons about as quickly as it comes out of
my 50 gal tank, maybe 30 seconds. I put the 5 gal pail below the
brewer outlet valve and hold the filter bag so the stream of tea passes
through it. A little shaking is needed sometimes to keep the
materials moving to the bottom of the bag. I don't substitute
anything for molasses, just use less of it. I've had good SFI
numbers using 2oz. molasses in 25 gals of tea starting with a few
pounds of vermicompost. > Dave > >
