See BeeHaus Manual.
BeeHaus is Omlet's commercial version of the DLD.
LDLD - Langstroth version of DLD.
I manage the LDLD like described by Dartington in his book or **Omlet** manual for their commercial version of DLD (Dartington Long Deep).
With two dividers I can home three 6 frame colonies. I designed 6 frame boxes so that 3 of them can be on the top of my 21 frame LDLD.
Original DLD uses British frames. I use Langstroth deep frames.
