I filled the container with cotton wool soaked with water, then added the seeds, I used Cress and Mustard sprouts.
Make sure you plant mustard seeds 4 days latter than cress to have them harvest at same time.
cover with a damp napkin and place in a sunny window ledge.
now if you repeat about every 4 days you will have a constant fresh spouting Cress and Mustard sprouts or what other sprouts you choose.
