Just set up a fodder system big enough to supplement my horses' diet! I lined the trays with paper towel to hold the seeds in place until they start to mat. I am going to mist them to avoid ruining the floor underneath. I've been misting my chicken fodder trays and it seems much more effective than watering.
I have a horse who has ruined his front teeth by cribbing and has trouble grazing so fodder may be a much needed boost for him.
