It has been my experience that the photosyntesis cycle directly controls
flowering.  With proper fertilization i.e. anything w/ plenty of iron,
starting with a light cycle of 

18 hours on and 6 hours off or  16h-on and 8h-off for about 2-3 months (
any schedule w/ more light than darkness, darkness being all lights off in
the tank room for the entire period, flashlights do not count as "moonlight")

Then move the light schedule to 12h on and 12h off.  This will resemble the
light cycle shifting from a Spring to Fall photo-schedule.  It is also
helpful use a blue spectrum bulb for growth and a red bulb for
flowers....Cool white or standard for the former and Plant spectrum or any
"pink-ish" bulb for the latter.  

Good Luck!

P.S.  Don't forget....the light schedule and light spectrum will also
affect the rest of your plants and your animals, to some degree.  Please
consider these factors before implementing any changes.
