molasis i think is just sugar for microbial gizmos, doesn't really improve yield i don't think, just allows the plant to better absorb nutes, though it probably doesn't do much of anything. nute companys started selling wattered down molasis a few years back for rediculas prices, if you ask me it's just them trying to make a buck and wont be helpful, the ants your seeing only want sugar and probably wont bother your plant, i wouldn't worry about them that much, but not using molasis will probably make them go away.
