Is see where you're coming from with Frost and Lunar. I put Lunar down simply because it was better than Wraith. As for the others, Smoke is literally the air (CO2 to be specific) released from fire. I can see it being used in a way akin to Darkness techniques, but that doesn't mean it should be one.

Mist is seen far more often than just when it's cold out. It occurs at the base of a waterfall, or even from a hose, to name a couple examples. It's just water particles drifting on air.

And Growth... well, I'm not overly familiar with Growth, but I'm fairly certain that it doesn't refer specifically to plants. It's a strengthening element, not just a plant-growing element.
