I've built a few 32 frame long langstroth hives lately, some for myself and a few for friends and I have been interested in the modifications that you can make. We've added grips for the planks that cover the frames, internal feeders, vented roof planks, bug proof footings, roof rests, and a viewing window. Additionally I am working on a queen excluder and a few other ideas. The long hive is a great design for us because we live in the middle of San Antonio and have neighbors all around and I am able to get into the hive without creating a big disturbance for the bees (or my back). I really do think this is the best design for new beekeepers and people who only have a few hives. The viewing window is also nice because even though the frames block most of the view you can still see quite a bit of activity in the gap between the frames and the window and in the hive itself, especially if you shine a flashlight through the roof plank vent and look in the front window at night. The comb bursts with light and you can see them hard at work filling my foundationless frames.. The window is obviously not necessary but I love to look at my bees. I'd love to hear about any mods that you guys are using or can suggest.
