Also not true. Or at least, not at anything 10-20C.

Anyways, I think this guy's issue is one of non-distilled water and containers which allow an ample exposure to light. One can buy 2gal of distilled water at any supermarket for around 2-3$. It's not that much an issue to worry about. Surely one can "haul" a gallon in each arm, or are we that lazy these days?
