The best way to know if the fermentation is done, is a week or so after you have added the honey check the SG, wait 2 or 3 days and check it again. If the SG is the same both days it is done fermenting, if it has changed the yeasties are still working away. So then check it again in another few days and compare that number to the second reading you got. If change then still fermenting, if no change then it's likely done. Keep doing this until you get a stable SG. This may take a while since honey can be slow to ferment (see: mead).
You will find that your SG readings are a much more accurate way monitor fermentation than trying to go by the number or absence of bubbles in your airlock. Though fun to watch, the bubbles almost mean nothing.
