I don't take issue with your statement, but if your using a carboy without a hydrometer, wouldn't there be other signs of fermentation. I always tell people to look for krausen or particulate on the glass.
Obviously there needs a hydrometer reading, but you can see signs of fermentation without. Just sayin.
