Yes you will want to have at least one of each in the beginning. Not only do they make pollen/jelly for more alvearies, but they are also excellent at producing honey that you are going to need quite a bit of for alvearies and bealizing for future breeding.Hey guys! I'm getting close to making my first Alveary ever! What bees do you guys recommend putting in there first? Imperial/industrous to produce stuff to make more alvearies? =P
Also remember it is rather cheap to upgrade alveary blocks to Frame housings. Adding just 3+ cheap untreated frames to an alveary will greatly increase its output.
