No real tips, apart from you have plenty of time to read Robin's book(let) on the DLDH. Lots of operating ideas in that, along with the 'thinking reasons' behind the bees' behaviour . I do my own thing with them, as they are my 'static hives'.
The one main thing I do differently, is simply use National supers - not those honeyboxes. They do come in useful for bait hives and keeping the roof level, but apart from that I find they are a pain.
OK if you really need the lesser weight of a half super, but I can get by without....
Extras:- Add a couple of under-floor battens so the floor can be sealed up if required, extend the roof sides so a wadge of insulation can be placed over the cluster and add some insulation on the sides, where the winter cluster is situated (the frames are brooded right to the edges even in early spring - just like a polyhive).
Heat loss can be further minimised by insulating appropriately at both ends, making sure there is no constriction to the entry/exit slot. Real cosy bees, real early starters in the spring-time - just beware of stores requirements with the early brood!
I like mine. Easy to work in the early spring/summer.
Oh, and remember these are top bee space (supers and any other colonies you may acquire all need to be the same, for ease of operation).
