Have Flow hive set up, installing nuc tomorrow.
The Flow screened bottom board has two positions (3 if you included board completely removed). One high up, effectively sealing the brood box at the base, and one a centimeter lower, allowing some ventilation, and maybe pest trap.
I am looking for advice on which position to use the bottom board.
I am in rural Australia, so varoa is not (yet) an issue. Currently very hot dry summer up to 40°C, warm dry nights. Winters cool (-10°C nights, +12°C days).
Hive is located in a position that is full sun for most of year, semi/dappled shade from noon to evening in the summer months. Hive is on a stand.
So, despite extensive internet searching, and asking locals, there is not a lot of consistent info on how to position the bottom board, especially one which has 2 slots as came with the flow hive.
Distilling it out (and ignoring pest monitoring for now), my impression is that bottom board should either be completely removed or slid into the lower slot in summer to help ventilation, and slid into the upper slot for the rest of the year. Is that a good starting point?
