I don;t see why you couldn;t grow in it... its certainly not very wide, but I don;t think that'll be a problem as long as you don;t let the plants get too huge...

as for lighting, kinda depends on what you want to do... HPS light is probably the popular favorite, i;m doing a grow with CFLs though, and as far as how much light you need, that will partially depend on what type of lighting you go for and how many plants you plan on growing. if you go HPS probably a 400watt if you have a few plants, or you could probably do a 250 if you just are doing a couple.. if you use CFL, I believe they say 25watt per plan minimum, but 50+ is recomended (this is actual CFL wattage, not incadescent-equivalent)
