not to be a copy cat , but as always i agree with dw, most chams are freaked out by misting with room temp water because of the temp drop upon atomization (a whole nother subject so dont get me started,) but often chams that seem freaked out by room temp water , will become accustomed to, or even learn to enjoy, mistings that are (in the case of hand misting) properly administrated (as dw described), and of the appropriate temp (as dw described), so heating of misting water (here i go) is strongly advised , this means cold water that has been heated, not warm water from the tap . this can be as simple as keeping your misting bottle on top of a small under tank heater or piece of heat tape, if that doesnt raise the temp enough then you can try wrapping your bottle with an insulative material like bubble wrap , you can also keep your bottle in a warmer location like next to (but not under) the lights. for most chams the actual spray should be in the 85-100* range/ edit ps heated water should be changed daily, or more specifically, every evening, so that it is warm by the next morning.
