There are some great ideas in this thread so I thought I would let everyone know what worked for me.
I soaked the seeds for 12 hours in a ball jar, rinsed them well and drained them and left them in the jar with a piece of netting covering the opening with a rubberband.
I left the seeds in the jar and rinsed them and drained them about 4 times over the next 24 hours while they sprouted. Be sure to put the jar upside down in a dish drainer in between rinsing - just like you would do when sprouting other seeds in jars.
Then I spread them out over the damp soil. I was worried that I sprouted them too long and thought they wouldn't put roots down into the dirt. But nature is so darn smart. The grass grew faster with no mold.
I use the typical tray with the holes in it but I also have a solid tray to place it in. When I water the wheatgrass I check back after 10 mins and drain the water out of the bottom tray.
