What Light Pattern?

ive just orderd this seed http://www.pickandmixseeds.co.uk/products/barneys-farm-little-cheese-automatic

I am very exited im just wondering a good light pattern for an autoflowering plant like this one. I believe you dont have to change the pattern as it is autoflowering.

P.S - do you think this plant will have a strong odour?

18/6 does the trick for me mate, The more light the better
