that's too small for an hps light. You need something about 5 feet tall if you're using a 250w. The 250 will be alright for 3-4 plants. If you want to stick with that plan, you need to get some fluoros/cfls, but won't get as good of a yeild. You can get an airpump, lines, and everything from a hydro store. pool/fish stores stores will usually have them too. Fan: get your lxwxh in feet and multiply them. Whatever it comes out to you'll need a cfm fan equal or higher. Also, get a oscillating fan to put in the grow room/box Nutes: all preference, pick whatever works good for others and something you'll like. You'll need a ph meter and an ec meter as well as ph up and down. Earth juice has organic ph up and down. I use that, and works good. Never mix up and down though. It's good to have calibration solution for ph and ec also. Just to make sure your meter(s) are accurate. It's good to have some cleaning solution too. Alcohol or distilled water are sufficient also. Temp: just find a heater with a thermostat and set the temp.
