Is there any reason not to dry hop in the primary after the fermentation has died down? I am thinking of dry hopping after day 11 or so, leaving it for another 10 days and then racking to secondary. Is that ok, or will I lose something?
The only problem I have ever encountered/heard of is when you dry hop before ferm has died down (which it sounds like you are not going to do). When you do that the CO2 being produced by the yeast basically causes gas extraction of the hop essential oils and will cause your dry hopping to not work very well at all. I dont know about them causing the yeast to function poorly but if you add them after fermentation is mostly complete it shouldnt matter anyway.
