Sprouting is AWESOME!! so easy to do and Nalani loves it!! One of the ways that helped her wean. I get a sprout mix from a local bird store. It contains black eyed beans, lentils, barley, peas, and a bunch of other safe and healthy bird beans/seeds.
I use GSE which is a grapefruit seed extract, it helps prevent fungus and mold. You can purchase it online, I found mine on Amazon for $10.
For the jar, instead of paying $12-20 for a sprout jar, I use any empty jars at home (spaghetti jar, nuts jar, sauce jar, etc.) and get tulle fabric or any net type of fabric and cut it to size. Then I rubber band it to the top as a lid and there you go, a sprout jar for less than 50 cents.
It's a lot of fun and birds LOVE sprouts. Which is great since it is so much more nutritious than just cooked beans...
