I suggest reading these forums, search for answers if you need help. There are so many different aspects you need to concider first. How big you plan to veg your plants, if your using 2 75w lights you need to figure the distance from the plant they will be compared to your total height. How big are you growing these plants? The lights SHOULD work, but depends on a lot of aspects.
If your growing your plants in a closet or some small area, then yeah those lights might work, but it all depends. You want to go organic or what, I dont understand the point of nuteless soil for a firtime grow, unless you plan on adding all of the plants nutes yourself. In which case you will spend more in extra nutes than a bag of soil with them already in.
Biggest things you need to ensure you dont cause. !) over watering (I would say mix your soil 50/50 with perilite) 2) underlighting (Your already worried, its understandable) 3) Nutes and defenciencies (Self explanitory, these plants are reseliant, but they still need things just like you or I) and 4) Fresh air, proper exhaust(You need fresh air for your plants, just as you need to push the fresh air out). 5) Do NOT over love them! (You will learn by what I mean).
I know its overkill for your question, just my 2 cents.
