You could switch them now. Horizontal hives are not for me. As far as weight of the hives I have mostly switched to 8 frame equipment over the years. I love 5 over 5 nucs as well, easy to handle. If beekeepers ask me about how to handle the weight, I just tell them to bring an extra box and take out half the frames first.One thing is for certain. If you donāt like it, you can switch back to traditional Langstroth. Otherwise, I wouldnāt be taking the risk. When you say the earlier in the year the better, would you not attempt it at all this year? Iām totally cool with waiting until next year if thatās what will be the best chance for success. Iām only 50 but it hurts my back to bend over those hives. Iām hoping this is the ticket to beekeeping thatās easy on the body.![]()
