No. Yes, get an hps or mh switchable ballast/bulb.

You can grow seed to bud with just cfl's but why??? Especially when you have such a grow space.

You need to research a bit what you can/should do with your space, even just look around the forum.

I don't mean to crash your plans but using CFL's the entire process isn't going to give you anything near HPS/MH. This is just a recommendation which you will probably kick yourself later for, trust me. Humidity gauge isnt necessary but you can get a mechanical one for very cheap <$15 and works fine.
