Hi, I am new to the forum. I have two backyard hives and I live in SE PA where the weather is fairly humid. This is my first year with hives. The hives are 8 frame standard issue, with screened bottom boards, notched inner cover and telescoping cover. Each hive is one deep plus one medium super---they started as four frames and have built up both boxes. Now that the weather is cooling down, I have noticed that water condensation is forming at the top of each telescoping cover and mold is growing. The water drips too off the top cover onto the inner cover. As you would expect, the moisture is worst in the morning after a cool night. Clearly the ventilation is inadequate, and this concerns me as I would expect next year for the hives to grow, creating even more condensation. So my questions are thus... am I correct in assuming that the ventilation is inadequate for the area in which I live? Should I remove the mite board that is under the screen, since that also blocks air moving upward? Would that not make the hive cooler in the summer too and reduce bearding? Should I cut another notch on the inner cover (opposite end)? I have to assume other people have this problem which makes we realize that hive designs are not one size fits all.
One other question--both hives are close to being fully drawn and I wonder if I should add another medium? It's rather late in the season so I am not sure this would be a good idea.
Thanks for any advice!
