it shouldn't be a problem with temperature. you can have it blow right at them but it shouldn't blow on htem very hard. it just neads to make them wiggle a little bit. That would be a realy good ligh to get, make sure you find a socket that will fit it though. i have been trying to get some 65 watt cfls but it has a big... idk what it's called but the part you screw into the socket is huge. That cfl would be plenty of light for veging 2 plants.

plus with cfls ytou canget them realy close to the plants without burning them. plus haveing alight close will make it grow more compact wich is good for saving space.
