I would stay away from the auto pots. They are a passive hydro system and the idea behind them is to constently keep a layer of water in the bottom of the pot and MJ does not like sitting in water that is stagnit and they will develop root rot. The T5 lights are OK, but you will need to grow about 8 to 10 small plants to really make it worth and you will have to adjust lights quite often. I would think about a 400W. They are cheeper than the T5's as well.
