Does Orange Juice Help Plants Grow?

I've tried this before and it did grow well, about as well as water but it had a bad smell and lots of mould though along with it.

NO, It's based on the composition and pH of the liquid. Plants needs water, that's it, just basic water.
O.J. And milk cause minimal growth because they are composed of other molecules.   Also, the slight acidity of O.J. Can have negative effects.
