Indoor newbie looking for help

aight iv grown outdoors a few times got good results, but here recently i decided to make a aero setup. This setup is in a 6ftx4ftx2ft closet. First grow on this setup im only doing 4 plants. Now the problem i run into is that im on a pretty strict budget and need lights. As i said iv always done outdoor grows and have no idea about what kind or how many of what lights to get. I dont want monster plants inside 3ft tall at most, but i want a pretty decent harvest. Any suggestions on lighting would be helpful, and if at all possible where to go to get the lights would be even better. Thank you guys in advance,

for outside growing all i do is wait till after the last frost of the year, plant my seeds either directly in the ground at 2 inches deep and water them, or i germ them inside using a paper towel and a zip lock baggy in a window seal and then plant them and water outside growing is pretty much plant and forget around here.
