22 mm TIMBER THICKNESS | 6 frames WIRED HOFFMANN |
217 × 159 mm FRAME SIZE | 400 g BEES TO STOCK IT |
Complete solid-timber hive in the Mini Plus format for rearing, mating and overwintering queens, with a mesh floor and six Hoffmann frames.
This is not a box you stock in spring and break up in autumn: the Mini Plus is a real small colony —bees, brood and stores— that comes through the winter and gives you queens the following season. In return it asks for boxes, feed and closer watching.
01 · HALF A DADANT SUPER FRAME
Each frame measures 217 × 159 mm: exactly half a Dadant Blatt super frame (435 × 159) and the same depth, so two side by side come to 434 mm. But they do not join together: they are timber, self-spacing Hoffmann and horizontally wired; the ones that clip in pairs are the 217 × 160 mm plastic half-frames. And a Langstroth frame will not go in: 448 mm against the 236 mm of internal width here.
02 · WHAT IS NOT IN THE BOX
What you get is fixed: a stainless mesh floor with tray and entrance block, one body, six frames, an insulated crown board and a roof. There is no feeder, no foundation and no bees. Feeding goes two ways: a frame feeder that takes the place of an outside comb, or a feeder box that sits on top. The reservoir holds around 0.8 L: feed little and often, not all at once.
03 · IT OVERWINTERS, IT ISN'T EMPTIED
You stock it in May or June with about 400 g of bees, a caged mated queen and a couple of litres of 1:1 syrup. Once four of the six frames are covered you add the second box; to overwinter you stack two or three, with 9-10 kg of stores inside. One overwintered unit yields six to eight mating nuclei the following spring.
04 · BARE WOOD AND OPEN MESH FLOOR
It ships in bare timber, unpainted and untreated: the maker recommends a wood stain or varnish before it goes outdoors — the point our one non-five-star review makes. The floor tray, left in, lets you count natural varroa drop; taken out, it ventilates in summer. The entrance block closes the hive to carry it to the mating site. And there are two covers, not one: insulated crown board underneath, 14 mm roof on top.
05 · BEFORE YOU BUY
Mini Plus is a closed format: only Mini Plus frames fit, and its combs are no use in a full Dadant or Langstroth. You get one complete unit, a single box: expanding or overwintering it takes further boxes in the same format. And it is not a starter hive: six small frames fill fast and force you to watch for swarming from late May.

Data sheet

Mini Plus nucleus designed to overwinter queens and have spare queens during the season. It requires little supervision and offers plenty of space, with the possibility to add up to 6 medium frames. It is a good choice for managing queens intended for internal use, and if they are not needed, they can be kept there without any issues. It also allows overwintering queens in colonies populated with 5 to 6 frames.
