I bought the plans for building a top bar hive and am putting in a screen bottom. I noticed on a video that they had a screen over the top vent holes also. I can’t find anywhere where it tells what size the screen holes are for the screen. I’m building a couple of hives for the university I work for to use in there new bee keeping class there starting this summer. Any help would be greatly appreciated. Thanks, Frank
Hello, Frank! Congratulations on your TBH Build! That’s a very noble, and satisfying experience of putting one together. The ventilation ports can any size you want, though we do 1" diameter, and the hardware cloth (screen) we use is spec’d at 1/8"! Let us know if you have any other questions.
