feed stock molasses question

[DCT]

i am getting ready for my 2nd gen rum wash, ist run was with expensive fancy molasses from store..I picke up 5 gallons feed molasses from feed store, 5 gallons has net weight of 50lbs...says 29% sugars from pure cane molasses &condensed whey soluables...will this work for my 2nd gen wash? I have 1inch yeast bed left in 5 gallon car boys, 4 gallons of dunder in fridge & 10lbs of brown sugar....question, i know the sugar content is lower than my fancy mollases from 1st run, how much of this feed molasses should i add to a 5 gallon wash? with how many lbs of brown sugar, & how many gallons of dunder?...thanks
