They collected as much information as they could find from reading books and surfing the World Wide Web. They thought that large boxes, housing lots of colonies was the way to go. A size that could just be assembled from conventional 8x4 foot sheets of plywood, particle board, and various insulations and plastics. The box has heavy insulation in the cover and insulated walls. By eliminating the wood in the frames, the owners feel they have the equivalent of 8-frame equipment.
Ventilation is through a single, good sized, screened hole in the bottom of each unit.
Large entrances of plastic pipe allow bees to fly out the sides of the box. Caps with various screen meshes are placed on the pipes as entrance reducers or closures. Honey production is a problem in this operation, since the system is geared specifically for pollination. Each colony must be functioning optionally to make the system work. That requires frequent visits to the bees.
