Okay - I'll be more patient. 48 hours and still no bubbles.
It is 6 gallons in a 6 gallon plastic fermentor. There is still about two inches of air space. The seal is so tight, I'm not sure how to get it off later.

If I press on the cover, the water in the airlock will move so I know it is tight.
The temperature is 66 degrees.
My two other 3 gallon experiments (made from scratch - peaches and bananas) are bubbling away. They started within hours of adding the yeast - that's why I was questioning the kit.
