Growing Pure Sativa Indoors

Hey guys, first time posting on here, kind of a noob to the whole thing tbh. I think i might have made the mistake of ordering budha 100% sativa seeds from marijuana-seeds.nl because it is supposed to be especially difficult to grow. I was hoping i could find some tips on how to follow through with this process. To give you my basics, i have a closet, probably just gonna buy regular soil and use fluroscent lights coupled with foil(another question is there a prefered foil type). If someone can help me out i would greatly appreciate it. I will provide pics of my progress for all of you who enjoy the mystique and beauty of this wonderful plant.

Go to my seedsman grow to see what I did with a Haze that is around 90% Sativa. I flowered around 9" or 5-6 nodes and then I let grow and began training it to the side so I could bring the light down to get to more of the lower branches and I got 2oz.'s exactly dried in organic soil and molasses. That the approach I would tak in terms of training it and bringing multiple light above and from below on lamp stands.
