I use the easy sprout and do rinse the sprouts a couple times a day. Instead of running a lot of water, you can put some water into a bowl, dump in your sprouts ... give them a "bath" then pour them back into the easy sprout (catching the water in another bowl). If you have more than one sprouter going, you can use the same 'bath water' for each batch. I like use the bowl rinse method because it uses less water and it allows me to swish the sprouts around to loosen them up. It is also an opportunity to skim off any hulls that gather on the top. I like the easy sprout because they have great air circulation and you can grow a lot of sprouts in a small space ... they don't have a large 'footprint' and you can stack one on top of the other.
I'm search the net to see if I could find anything else about 'dry' sprouting, but nothing came up except the link I already listed above.
Cheers
