Do your homework before you buy one single thing! If you go willy-nilly buying things (especially from HD) you are probably going to find yourself with a bunch of stuff that you cannot use. I would not use anything called a "plant light". They are generally not good at all. T5s are the most efficient of all the other fluoros, being about 50% more efficient than CFLs, T8s or T12s.
I would highly recommend that you do some reading to learn for yourself what you are going to need to grow. No one else can really set up your grow for you--each space is individual and has special needs. You need to pick out a space that you can light adequately, you are going to have to set up a ventilation system, pick a growing method, and get all your supplies. If you are growing soil, read up on soil mixtures. Potting soils with nutrients already in them can kill seedlings. If hydro, check out different systems. Your flowering space is going to have to be a place that you can keep 100% (and I do mean 100%) dark for 12 hours straight.
Do some planning before you buy and you will be a lot happier....so do you have a space picked out? How many sq feet is it? That is the first step. How much money do you have to spend on this project? It WILL take an investment of money, time, energy, and love if you want to end up with anything when you are done....4-5 months down the road.
