@NBasseur The airlock is a pretty poor measure of fermentation, but if you insist on not paying for a hydrometer, time the bubbles until you are getting less than 1 a minute. It should be safe to bottle 2 week later. 
@Walzenbrew Lots of people over pitch and make fine beer. The main side effect I have heard is that you are shortening the reproductive phase and you will have fewer esters, which may or may not be desirable depending on your taste in brew.
