If you want plants eventually, save your effort & just go with the fluoros.
The lights are in fact replacing the sun in your aquarium, they just don't
have the same sort of intensitry. There is still a minimum intensity for
each plant species though & if you don't achieve that you won't get plants
to grow. The lights provide energy for the plants to convert nutrients into
plant matter. Without enough energy the plant can't use the food you provide
& they will eventually die.
If you try to do live plants with LED's be prepared to spend big, . have a
suitable spectral output for plants & can provide the kind of intensity
needed is still in it's infancy so they are very expensive. Commercially
made LED fixtures that are suitable for planted tanks cost thousands.
