I'm with the others yielding enough smoke for 3 people is not going to happen with a cfl set up, your budget is far to low you may be able to get some but you will be fighting a losing battle with your budget every day, there are certain things that are must haves and I'm afraid that your budget would barley be enough to cover them let alone good equipment. I have a 5 foot by 2.5 foot by 8-9 foot closet and i had 8 100 watt cfls in there and it was way to hot i had to vent it, as far as your question about light bulbs goes you would want 100 watt equivalents or 23-27 actual watt cfls, as far as the spectrum goes you need 2700k for flowering and 6500k for veg, also those 13 watt cfls are useless.
