Save yourself all the work like LOC says.Do the whole thing indoors.Can you see yourself having to tote all those into a room.If they are sitting there already,Then ya flip tha swith on'em.You will have more time to yourself if you keep them in a controled environment.They are gonna get way way bigger outside than indoors.your room won't be enuff.Not to mention a 400 or even a 1000 would do them justice after being outdoors.
