Day 5

Five days in and those little anemic blades are thickening up.  I'd say they are two inches high. 

I've read it's essential to rinse the sprouts twice a day.  We've started using the rinse water from the milking machine.  Just before we use the machine, we rinse it with sanitizing water that has a small amount of chlorine.  We figured that sanitizing water would help hold down mold and bacterial growth in the sprouts and it's recycling water.  So far so good.
