[compost_tea] wire/poly gauge
dennis:
good point, actually. I didn't substract it...:) I wonder how many deniers =
they are...(letīs spot the over-40's here,lol)
guess if Dr. E. could publish the whole conversion chart for us non-SFI adv=
isors here, it would help a lot , and put an end to this mess-hy thread:)
jeff's chart does not go above 40 mesh, and can't figure out how to extrap=
olate it...
cheers

--- Alex, Did you subtract the diameter of the wires/poly? I have to
guess the #12 mesh screen I ordered from Banjo (mfr) is around 1000
to 1200 micron. Banjo does not give the opening of the #12 screen. I
am making the tea in the application tank and therefore use an in
line filter prior to the pump, pressure regulator and nozzles. My
nozzles are 1/16 inch (measured with a 1/16 drill bit). I think some
1/4 inch by 1/16 inch fungi will make it thru the #12 screen
provided it has a 1000 to 1200 micron opening and sprayer pressure is
low(I don't know how low). The reason for my concern is I have farm
ground (and perennials on non-farm ground)which has been tilled for
years and it probably needs fungi so I don't want it plugged in the
screen. Dennis Kemnitz
