You didn't say the size of your room or how many plants.

I would get the biggset light I could but that's just me. Overkill.

You need good water and some GH 3 part nutes and cal mag plus. don't try to over do it with additives untill you have a few grows. If anything goes wrong then it is easier to find the problem.

A PH meter is a must and PH up and down.
