read some grow journals before you start to get an idea of how experienced people grow. It will save you time, money and hassle in the long run. The fact you dont know what nutes are says alot. i have several journals linked in my signature, look through them and you will find answers to all your questions.
Its possible to grow under cfls but for anything decent you want minimum 400w hps per square meter but i dont use less than 600w hps. You could also use led but again the same wattage applies, just make sure if you chose led that its the actual power draw and not inflated numbers from manufacturer.
