Is there anything i need to take into consideration before adding pellet hops for a dry hop? I have 5 gallons in a 6.5 glass carboy, its been fermenting for a week, and the bubbles have died down to about 1 per minute. Is it ok to add them now, and any good techniques on adding them? Im a little worried about pulling the carboy hood off and the 3 piece airlock water sucking into the beer.
