while i agree with Dutch, HID light is much better, you can still definately
flower with those lights you already have. the buds won't be as big, or as
dense, but you will like smoking them, lol

i use CFL's myself because of budgetary constraints and, while i wish i had
the dough to throw down on a 400watt HPS, i've grown some killer buds
from some bagbeans with nothing but CFL's

also, heat is an issue with fluoro's as well so put your hand near the bulbs
and if they feel hot to you, they will burn your plants. i only say that 'cause
i see in your pics that the leaves are touching the tubes.

check out my imaginary garden to see what i've done with nothing but CFL's
