I personally don't like the jar method because I mostly sprout beans and sunflower seeds. I feel I have more control in bowls, sprouting just individual items, like I said.
As soon as tails form, refrigerate, regardless of what you are sprouting. Since sprouts are alive they will continue sprouting in the fridge. If you only sprout a small amount at a time you won't have to worry about them going bad, but you should feed them in 3-4 days. I usually start a new batch every couple days. It becomes simple once you get in the habit. IMO it is much easier than cooking beans. Just remember to rinse everytime you take the container out of the fridge.
Also, they will continue to grow in the food dishes, so you don't need to worry about them spoiling there either.
Oh and btw, lentils are kind of spicy, garbanzos are rather bland and mung are sort of 'fresh'. I use them on my salads also. In fact, I often eat a bite of the food I serve the Eclectus because it is basically a salad with a bit of cooked grain; granted a salad with greens, veggies and fruits, none of which we normally serve mixed together but it's fresh and tasty!
