How many CFL's??

hey, I have nice ourdoor plant, about 4ft, healthy, that im goin to be bringing inside for the last 2 week or so of flowering since it'll prolly snow soon. Im just gonna use some CFls since its only a one time deal and its only one plant. How many bulbs should i be using and of how many watts?? Does anyone know of a good homemade CFL setup with reflector I can make?
Thanks

i was informed of about 2k lumens per square foot of plant.....look at the bulbs before u buy and look at the lumen count. probably go for the 40w cfls those will pump out sufficent lighting

2000 lumens shouldn't matter that much. it depends on the par rating. flouros have high par rating anyway but honestly man you should have at least 400 watts. get as many cfls as you can for a 4 foot plant
