Looks like a good start. I would drop the water level significantly though, standing water is no good with emersed plants IMO. Is this strictly for emersed growing plants to transfer to another tank, or is this a dry start tank? Also, dwarf baby tears grow well emersed.
I don't know if the kitty litter with tank water will provide enough nutrients, but I could be wrong. My emersed setup has only been going for a couple months now, so I don't have a lot of experience with it.
