>I was told that feeding straight granulated sugar was harmful because they can not digest it or something like that.
They can't eat it without water, but they can't eat honey without water either. They won't take it as rapidly as syrup. I'm trying it after seeing how well candy boards worked on a friends hives and decided I was too lazy to make the candy. And I expanded and don't have that many feeders. I hadn't planned on feeding, but the failure of the fall flow forced my hand.
