For your information:
Hive gained 11 pounds in a single day, this day, of feeding: 2X sugar solution. I began feeding yesterday Tuesday: 2X sugar solution; 10 pounds sugar to 5 pounds water [5/8 gallon] in 4 open community feeders.
I did place the feeders away from the hives. After I set up the feeders, several hours passed and no bees. So I placed one drop of lemon grass oil in front of each feeder and wham, in minutes I saw scout bees and in no time, the feeder became buzzing with honeybees.
I was surprised by 11 pound gain in a single hive in a single day. I would have guessed much less. In 48 hours my 18 hives have consumed almost 50 pounds of sugar, 5 each 10 pound bags of sugar, not counting the water. Of my 18 hives: 6 are nucs, 10 double deeps, 2 single deeps. The weight measured hive is a double deep.
My Bees are in a heavily wooded area with very little Fall flow, goldenrod is seldom seen within 2 miles of my hives so I have to Fall feed.
Blessings
