If you can afford it the 400 watt hps is the way to go, floro's work for seedlings/clones/mothers/ and growth, but not so well for flowering. A 400 watt hps will give you enough light for 9-10 plants. Later you could always buy the 400 watt mh [ i use this exact same set up 1-400 hps and 1-400 mh] you could then double the size of the grow and number of plants. switch the lights every few days so all the plants get both types of light,
giving you a nice sized 3x6 growing area.
