Plants grown under cfls will have fluffier(less dense) buds, generally wont produce as much(went compared to hps), and will take a bit longer to mature(again, when compared to hps).

Can't really say how many lights you'll need, it has a lot to do with your grow space. Refer to the lighting FAQs.
Orzy Reviewed by Orzy on . First time grower - Check list Ok, so I have either the option to grow in a little closet, or in my attic. Which would be better? Also, because they use such low amounts of electricity, I was considering starting off with CFL light bulbs. Is this a good route for beginners? Also, what kelvin should I be aiming for?
