I meant to say presoak. The napkin in top keeps it wet and under pressure speeding up the process. I get a 50# bag of wheat for $11 locally. I'm using an old metal shoe rack with three tiers and ten using a strong plastic bag at the bottom, zip tied to the corners to catch the water. I poke a hole in the middle of te plastic so the water doesn't go all over the place. I recycle the water until it looks yucky and use fresh water every few days.
