Is more intense light really needed to grow algae or just longer hours?

For my daphnia culture have a plastic garbage pail with a 100 W bulb mounted 
in the lid.  I fertilize with a little garden fertilizer and leave the light 
on all the time.  There is plenty of green algae growing on the sides and 
surface and lots of daphnia.

I would love to get the green water, suspended algae.  I guess I have to 
wait for spring to get a wild culture.
