ambient here has been hitting 75, i have 2 vinos with 65% beads, 1 with 70%, and one with 60% for aging. each vino has a pound and a half, i noticed a pretty big difference when i added another half pound, especially with recovery times. all temps set at max of 66 degrees, plugged and packed full and have never had a drop of condensation on the bottom. feels like i wasted time plugging and building runoff ramps. however i havent had to water in the last two months. i think its your low temp that's doing it, working overtime to keep your settings, but definitely add some more beads and spread them out over different levels. if packed you might also make sure you are getting some decent airflow, try leaving a clear path of some sort from the back fan to the front door, that will keep it from working so hard.
