+1 on the rice hulls. and watch the sparge closely. if you maintain an inch of water above the grain bed should be fine.
Unless he's batch sparging....
Okay, this raises many questions for a noob. Should there be more than an inch of water above the grain bed when batch sparging? Was he referring to the amount of water left on top after the grain bed has settled right before lautering or is the one-inch rule referring to continuous sparging? I'm getting ready for my first all-grain brew as well so I'm not well-educated even though I've read up on the topic.
He was referring to continuous or "fly" sparging for the 1 inch above the bed thing.
As for batch sparging, you do not need 1 inch of water above the grain bed you are merely going to use x amount of water in your main mash, collect: then use x amount of water in your 2nd mash(or sparge) to achieve your desired preboil volume.
So assuming the grains will absorb 1 gallon of water
10 lbs of total grain
1.5 qts/lb mash ratio
6.5 gallon desired preboil volume
You would use 3.75 gallons of water for your mash and 3.75 gallons of water for your batch sparge. It is also preferred to use a strike temperature on your batch sparge volume that will allow the temp of the mash to raise to 168-172.
There is no right or wrong way to do things, its all about preference on your system.
