Re: Screened bottom board - when should the board be in vs. out?
Bison, im across the bay in Livermore and although ive only been at beekeeping for a year, I dont use the slider boards at all and have not lost a hive to being "over ventilated" at all. Infact, I havnt lost any of my 5 hives yet! <knock on wood>
I wouldnt worry about using them here in the bay area, we dont have weeks on end of below freezing weather like the great white North!!
Coyote Creek Bees - Beekeeping for 3 years. Number of hives - 17
