Takes a 1/2 cup rinse of fresh water twice a day... a 1/2 matchbox of mixed seed turns into about 3/4 of a gallon of spicy green sprouts that can be eaten raw or mixed with other things. Takes about 5-6 days, and maybe about 4-8 pints of water.

I tend to pour the water off at home... but I suppose you could use it for flush water in the head... and conserve every drop for that use after you've rinsed the sprouts.

Sprouts provide a good way to "get your greens."
