Well patience is the key alright. About the lighting though... What kind of lighting is "the bulb" you'll be using. I ask because low lighting can be problematic even with only live rock and sand, not to mention fish.
I had a system where the lighting was too low and it never cycled correctly and red and black nasty slime algae was killing the soft corals and leathers, which are the easiest to grow.
I retrofitted my latest tank, an Odyssea B60 Bowfront tank. That system had a canopy with compact flourescent lighting. Only one of the two bank lighting system worked (each bank had two 36 watt compacts) so that's why I replaced it with LEDs (a 120 watt EVO system 50/50s), but even with only the two 36 watt 50/50 actinic/blue bulbs I could still grow soft corals and leathers in that tank along with nice coralline algae on the live rock...
