Yes...Here's what I do:
I fill a spray bottle with room temperature water.
I pour all my grain into a tub, like this one:TUB
Then, I mist the grain & mix...
Then, I grab a handful & drop it.
If it starts to stick to my hands, it's wet enough & I stop.
(Don't over mist...Your mill will with gum up as if you poured concrete into it.)
I then let my grain sit & absorb the mist, while I heat my strike water (usually about an hour).
After sitting, it's ready to run through the mill & the moistened hulls allow you have a finer crush, while leaving the hulls more intact...Like stated, above.
