Finally, my first grow with lights!

I have 2 26 watt 6500k CFL's. Should that be sufficient for just one plant? I know growing one plant isn't very smart (eggs in basket, etc)...but since this is my first go I just really wanna see if I can grow this girl.

I have it in a 16 oz cup for now, been going on my windowsill since germ. Its in a coir/vermiculite mix that I made up myself (left overs from mushrooms).

My main question is about the lights though. Should that be sufficient for just one (MAYBE 2) plant(s)?

Also; I heard that 12/12 is what people do if they just want a single branch grown. Is that true? I'm looking to try and do something like "raeman1990" did in this thread: 16 oz cup grow contest?

THANKS FOR ANY AND ALL HELP GUYS! I APPRECIATE IT!


Also; is there any way to do it FULLY organic? Meaning, what should I use for nutrients etc? I want to try a bare minimum grow to see what the buds are like. I have a feeling what I usually smoke is processed and done all kinds of horrible things to.
