I plan on placing a hive on the roof of my home for the sole purpose of the pollination of my blueberries, grapes, cherries, raspberries, blackberries ... and garden on my 1/4 acre property. The question is what size of package bees should I purchase if I set of a 5-frame nuc? or 8-frame nuc? I don't think I'll be needing a full-fledged hive & I really don't plan on taking off any honey. I really wanted to keep the colony to a single brood-super size, as my needs are for only polination, but I suspect it would at least entail a second brood super? Any insight.
