After extensive reading, I’m convinced slatted racks are beneficial in this hot climate. So I’m going to make one for each hive.
So far I figured out that the depth of the slats at the top should be 5mm, but does it matter what depth is the bottom from the slats?
I was gong to use 42mm deep timber for the frame, but once the slats go in (19x19mm) the depth of the bottom will be only 23mm. Is this enough, or is it better to use 60mm timber for the frame so there is more space for bees to hang out?
Another question - which way should the slats go? This way or that way? Does it even matter?
