Hey the benefit of adding mesh foors/vents for me is i make up nucs all day and drop them at a yard at the end of the day bang cage queens in good to go if I wasn't making nucs for production/sale i wouldn't bother venting them if im overwintering autumn nucs i cover the vents up ,an easy way to vent them is a hole saw drill set, pretty simple and the smaller vents doesn't compromise the strength of your nuc floors
