Re: Electrolyte/Vitamin Supplements
J, I have been using the Agrilabs Vitamins and Electrolytes Plus supplement for about a year now. 1/4 tsp per 10# of sugar. No need to use it when feeding Ultrabee powder or patties as they contain the same vitamins. A bag is really inexpensive, like 4 bucks, and will last a season or two depending on how much you feed. I cannot say for sure that it helps, but the bees sure seem healthier to me, ie, more vigorous and prolific (no observer bias here).
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
