Coraline algae growth? how can I help it along

[BCOrchidGuy]

Well, I got my tank delivered tonight and I'm planning on using an idea Buk a neer used, or similar. He made an aragocrete back drop for his tank but I was thinking of using egg crate and covering it in silicone and then covering it in aragonite gravel. I figure I'll have some holes etc but alot of gravel on the back panel.
How would you encourage coraline algae to grow on this panel, so it doesn't look so stark? I'm also planning on using a large portion of base rock and maybe drilling holes etc through it to make it more porous but obviously I'll want the coraline to grow on it as well.

Should I start out with a couple NO fluorescents of the daylight variety and a couple of actinics?

Any thoughts would be appreciated
