I don't have any experience with Easy Green -- but, if you want something cheaper than an auto-sprouter, I would check out a small tray sprouter. It drains much better and more evenly than a jar sprouter, and that may help to ward off mold.

(Another technique that helps to avoid mold is the careful and diluted use of food-grade hydrogen peroxide to rinse your sprouting system and your sprouts at the very beginning of the process.)

I've had lots of success with a small Burpee tray sprouter I got for about $13. You can even find tray sprouters at Amazon.com, just search for "sprouter." Wheatgrasskits.com also offers a variety of sprouting-system options (along with a lot of organic seeds and beans).

Hope this helps!
