Is it just a single bulb fixture? If so, it probably is not enough light to grow any but the most light tolerant plants.

From the information you gave, F15T8 indicates that the bulb is 15 watts.

I believe the highest normal wattage for CFL bulbs that I have seen is 26W.

For a 20 gallon tank, I would go with fluorescent tubes, not CFLs. This is because CFLs tend to concentrate their light on one part of the aquarium, rather than spreading it evenly throughout the aquarium.
