I believe some photosynthetic animals require mild amounts of UV
and that is why marine tanks must use Actinic bulbs.
Rest assured that your plants will do fine without UV
. I've grown cuttings in 2 liter pop bottles under regular incandescent plant lighting without issue.
Most aquatic plants utilize chloraphyl for Red
light. Some true underwater plants also used Green light because Red light does not penetrate water well. This is why the custom tri-chromatic aquarium bulbs work so well, they have well defined spectra that provide plentiful amounts of each light source for plants.
