My place has tons of trees, and only the front yard where I mow gets something like full sun. I tried one box last year right in front of the kitchen window, where we could all look out the window and see the bees coming and going, that has about 3-4 hours sun, and I got tons of honey from it, but then, 2 weeks after harvesting the super , the bees swarmed and left. Now, I am getting ready for next year, and want as many as 7 boxes, but, again, I have very limited areas that have good sun access. I did invest in the whole miller beetlejail and beetlejail bottom boards, with all kinds of cool built in oil traps. Also, I have glued and nailed on 2 inch closed cell foam to the outside of my mains and supers, so that they would stay warmer in the winter and cooler in the summer. I am in the top right hand corner of Florida.
