My spare bathroom tub serves as my fermentation room. No windows and temp controled. I keep water in the tub that allowes the liquid to ferment at 68 consistently. For the sake of space I would like to move the carboys out of the water after 2 weeks to finish out their time in the primary. The thermometer reads 73 when out of water. Is it ok to do this after the fermentation has stopped or will I cause off flavors?
