My original Sensei was an older Dead Head stoner. He said he tried molasses but did not know if it works or why Nice guy, at times, but often useless and not particularly honest.
I actually looked at the label. Molasses has sugars and carbohydrates plus potassium, iron, sodium, magnesium and calcium. Brer Rabbit at Wal Mart is about $3.48 but you can get a cheaper brand at the Dollar Store. The darker molasses the better and the best is black strap.
One person on the DIY web forum here talks about doing a clone of Terpinator which is pretty much molasses and brown sugar. He purchased Potassium Sulfate (?) instead of molasses and brown sugar. I don't think molasses could hurt.
