I've grown them with and without soil.
without - had them sitting on flywire screen that was jammed into a plastic box. Showered water over the seeds twice a day and the box caught the drips. This method was clean and fun and did a big quantity, but it looked ugly.
with - scattered them on the surface of potting mix in shallow trays. Misted them twice a day. This method was fiddlier but came up with a presentable little tray that looked nice on the kitchen bench.
Harvest by cutting the sprouts off from the root/seed base when they are about 2 inches high. The taller the sprouts grow, the harder and waxier they are.
