ok so i was thinking about either running 4 400 watters or 3 600 watters, which would be better, i know i would probably get denser buds off of the 600's but i would get more light coverage off of running the 400's and the 400's would give off less heat. but how would i go about finding out how many watts each room can handle, or would i try to find the wattage of the whole house?
