Well if you dont have much money to spend on supplies, then for 2 plants I would suggest:
at least 3 cfl's per plant
Miracle grow soil organic kind, or the reg but if you can get organic go for that, and yes I know I recommended MG soil depite the rumors and bad feedback it actually is a good soil to use if you can spend the money for the more expensive bags. On top of that it has enough food in it for its entire cycle pretty much.
PH tester!!!!! and PH up and down!!! You could use baking soda and white distilled vinegar to adjust the PH if your strapped for cash.
Do it that way and it will be a learning experience without spending too much cash. While you work on those you can do more research get more knowledge under your belt for your next grow
