I was milling 2.5kg. I usually condition by mixing by hand in a bucket while spraying with a spray bottle. It takes a bit of time and my hand gets tired pumping the spray bottle, so I wanted to try a new method.
I'll reiterate though, that the wet (damp?) grain went through once at 1mm (0.04") with no problems. I believe that's a "standard" gap for most mills, and that most people only crush their grain once anyway. So under "normal" conditions, wet-milling seems to work fine.
When I condition I can run it through at 1mm and then again at 0.5mm, and it was only when running it through twice while wet that the flour became a problem.
