I'm relating all this to the reporting method in
SFI's compost tea reports. They use the term (ug/ml) but I suppose
you're correct that it is on a wet basis because they start with 1 ml of
tea. So the 0.67oz. of microbes produced are wet slimy guys. The compost
report seems to be adjusted to a dry weight basis. So, to compare the
microbes in the starting materials to those in the finished product we have to
know the weight of the water in the microbes from the tea. And, back to
the orginal point about adding sugar, 2 ounces of syrupy molasses is producing
much less than the 0.67 I stated. Am I right yet? I really do
want to compare what is in the compost a the start to what is measured in the
tea by the lab. Am I growing stuff or just extracting it??

---Dave in the ex. below you converted volume to
mass. Therefore 0.67 oz.(mass if you will allow me) in 25 gallons would
convert to 200ppm (mass). What I'm wondering is are those
microorganisms dry or wet? I'm guessing they're filtered and wet.

it. Sound correct? > > Dave > -----
