Here's something that I always refer to:

you need to know the total wattage of all the connected equipment to the circuit you want to use. this means wattage of the lamps in the ceiling light in the room, any tv's, pc's, alarm clocks, fans etc etc. heres why-
for growing, your electrical service must be rated for what is called a continuous duty factor. this means for each circuit you want to plug lights into, you can only use 80% of the available amperage the breaker allows. heres 3 common breaker sizes, and there max power ratings for continuous duty factors @ 120v:
15 amp breaker = 1440w max
20 amp breaker = 1920w max
30 amp breaker = 2880 w max
as you can see, if you only have a 15 amp breaker feeding the room, you dont have much wattage to play around with.
