3.1.2. Size of testing station

The number of colonies in the testing station should be at least 10 (representing different sister groups), to allow for statistical calculations (see section 4. selection tools), while the maximum number should be obtained by considering the minimal honey flow potential of the area (sufficient nectar for all colonies throughout the season) and the number of beekeepers involved in the testing. Usually, not more than 30 colonies should be placed in one test apiary.
