Also i read that you used rice should i do that to? How many bubbles should the diffuser be producing? Thanks!
They aren't very expensive at all actually. Just a few bucks. The glass ones will be just a little bit more as you can usually find them under $10 (not including shipping though).

The overall mix should last you several weeks. However, your results may vary depending on such factors like room temp and such. But generally speaking, a few weeks is a good bet.

I do use a small amount of uncooked rice and this seems to really help the mix along. The yeast breaks it down and turns it into sugar which then is consumed to make CO2.
