Hello Yunzow,
I don't know if I understand your question correct, but if I do, Vance G's and Akademee's answers missed the point slightly.
Q: How long does it take bees to convert nectar into capped honey? I was just wondering how long this usually takes, on average.
A: (kind-of) As I understand it, the bees take the nectar (and/or pollen) from the flowers and Google says: 1. Foraging worker bees fly from their hive (sometimes miles away) to gather nectar from flowers and other blooming vegetation.
2. Once enough nectar is collected, the bees bring it back to the hive. 2. The nectar is chewed up and deposited into honeycomb wax cells.
So, by my understanding and knowledge the honey production is a daily thing, over and over again until the cell is filled, then comes what Vance G & Akademee say, the dry-down process and as they stated, that depends. I assume many bees could fill a cell in a day, the dry-down depends and the 100 lbs or more in a season per hive depends on where you are, how many active bees you have in a hive and what the weather is like.
My bees in southern Alberta (north of the man-made 49th) take 2-3 month to produce +100 lbs of great honey.
So, I may have missed the question and apologies to Vance G & Akademee if I have offended them.
