Yes with respect to dry start, i dont think you have anything to worry about with using 2x18w.

Also remember that when you fill your tank, not as much light will reach the bottom and you may think its not so bright. You'll need good light (along with your ferts and c02) to keep that HC carpet nice. I would say, let your plants tell you if its too bright or not.
