The way I sprout my seeds is to soak them overnight in a small jar. I use 1/4 cup of seeds per tray. In the morning, I transfer the seeds to the tray. Then I rinse and drain thoroughly. I continue a rinsing/draining every 12 hours, or once in the morning and once in the evening. If it isn’t too cold in the house, the seeds’ growth will be slower. We eat them (at least this mix) when they have their first green leaves.

I discussed it more in depth here: http://gnowfglins.com/2007/09/22/microgreens-progress-and-a-bit-about-sprouts/

I wonder what your house temperature is? The new seeds didn’t do any better? How long did you soak the seeds?
