Yes, wheat malt is huskless.
I had mentioned a quarter pound, then prompted wrt the huskless mash (!) went to a half pound.
A full pound would be well over the top, imo. Even my gooiest 10 gallon batches only use a pound...
Here's what I'm thinking. I'm going to swag some numbers, for illustrative purposes. (All assuming a 5 gallon batch, with 10 lbs total malt) When we do a mash with "X" % of wheat malt, and get away with no rice hulls, it's because the husks from the barley malt have what we can call "excess lauter aid capacity." Since many people do 50/50 mixes without trouble, but many others do have trouble, let's call 50/50 the average max. Go to 60/40 (6 lbs wheat malt/4 lbs barley malt), and let's say we now need a quarter pound of rice hulls to avoid a stuck lauter. What this would mean is that
one extra pound of wheat malt forced 0.25 pounds of rice hulls.
Now, with the above theory, how much would a 100% huskless grain batch need? 10 lbs huskless grains x 0.25 lbs rice hulls per pound of huskless grains = 2.5 lbs rice hulls? We can substitute any numbers we want in the "model," but the important point (if true) is that when we add rice hulls, it's to cover the amount of huskless grains
over and above what the barley malt can handle with its own excess lauter aid capacity.
