I know a lot of beeks don't believe this helps but I do.So I plan on continuing this practice because I do think it works. Overwintering with 2 deeps its pretty simple, just swap the bottom with the top when the time is right .My problem is I overwinter with 4 ,8 frame meds.and there is not much info out there for med. 8ts only for the normal 10 frame deep. .What would be the correct way to reverse these ?I have taken the top 2 boxes and reversed with the 2 bottom boxes and then a few weeks later I will swap them back and so on up to 3 or 4 times. I have swapped the top box only with the bottom box the first reverse and the following reverses only bring the bottom to the top.I have done this both ways and I know the main thing is not to split the brood nest.Is there any other med. 8 frame only beeks that have experience reversing your med.8 frames and how do you reverse.
