Combine rolled oats, wheat germ, coconut, sunflower seeds and peanuts in your slow cooker.
In a small saucepan melt together the peanut butter, brown sugar, oil, water, maple syrup and cinnamon, until well blended.
Pour peanut butter mixture over the oats in your slow cooker.
Toss together until everything is well mixed.
Cover, leaving the lid slightly ajar to allow moisture to escape.
Cook on LOW for 2 to 3 hours, giving it a stir every 30 minutes or so. It's done when the granola is golden, dry and smells wonderful. Cooking times will vary greatly depending on your slow cooker. Keep an eye on it so it doesn't burn, especially as it gets closer to being done.
Spread the granola out on a cookie sheet and let it cool completely.
When completely cool, store in an airtight container.
