An alternative suggestion: I bought this humidifier for my chamber. It has an attached hygrometer and will in theory shut off and turn on the unit to keep a set humidity. I haven't set it up and started using it yet so I can't vouch for its effectiveness but it would be much easier and cheaper all around to use this. It also has a larger basin, which will save you effort. If you can return the one you bought then I would just get this one and try it out.
