try a sample in a gallon wide mouth jar covered with stocking .mite keep out the "bugs".you can fill and rinse without taking it off. if that works go bigger
yep you want to keep covered, I thank spicy, I run threw two wooden rollers comes out looking like "flaked" or"roiled" some scotch/irish has it added.not as much enzymes as barley.
I malt corn in my garden. I rototill an area approx 6'x6'. I pull the dirt back about 3-4" deep and line the hole with an old blanket. Then I spread 50 lbs of feed corn and cover with another blanket. I wet all of this down and then cover with the dirt I originally pulled out of the hole. After 5 or 6 days I check daily until the malt is to my liking. It works like a charm and has never failed me yet.
