Just want some feed back on my setup plz!

so i just finished germinating 2 seeds and they are currently in some soil for the time being... im was thinking of doing a hydroponic system and just wanted to know if there were any other items i should get or advice before i make my purchase.

items include:
Sun System 2 - 250 watts HPS
1'x1' ebb and flow system

obviously there are a few other things but these are among the most expensive that come to mind any other info or recommendations would be greatly appreciated!

Thank in Advanced

read hydro grow journals for the best advice that has already been given. what do you want for feed back? set up your grow room/box, and ill let you know how it looks.

some things you may need:
fans
y-splitters
nutes
rockwool
mylar/fire blanket for reflector
cfls and hps work well together

thanks for the info grow room will be a closet 5'x3'x8' tall, completely with some drapes hanging down from the inside and from the outside to ensure no extra light during "night time", and i have a fan already just need the hydro kit and lamp witch come out to about $300 that sound about right? only going to be growing 3 plants at a time so i think the 1'x1' should work out fine, just going to divide the remaing space for clones and flowering. I'll post some pics of the lovely ladies in my life!!!
