How have you done yours Neal?
I chickened out of doing UFE's last time because I was concerned about the ports becoming blocked with carcasses on some of the designs on t'internet-bits of pipe and mesh boxes.
I dont need help killing my bees, Ive got that covered...
Maybe next time.
I have floors of different hights too and its frustrating.
For now Ill just build up the shortest ones up to the same as the tallest one and have a go at underfloor when they're due for replacement.
Purely by chance all the varroa boards are already similar to the point of being interchangebleish
