lowryder 2 outdoor grow (1st grow)

this is my first grow and i recieved my bagseed today from drchronic, in only 1 week!!! i am germinating the seeds right now under my bed. a few questions were:
i am in very rocky soil on top of a hill what should i use as a topsoil or something?
Also would it be better to get morning sun or afternoon sunlight because i have to choose which edge of the clearing i would like to be on?
