looking up blackstrap
save your money, read up on blackstrap molasses...
I am using the Soul Synthetics Big Swell. It works much better than the Nectar lines. It has a good amount of sugars in it and you don't have to worry about it clogging up pumps. IMO of course. It is expensive though.....50 bucks a quart.
Soul Synthetics ok is this your first time useing it
