Please!!help!!!Building my own hps system

What would i need for a cheap hps system help appreciated with home depot supplies..

I think home depot has 450watt hps lights, ballasts, vents, fans, etc...

How big is your room?

well i plan on converting 6x6 basment intogrow its actually bigger but i think that will suffice

you should consider using an 1000 watt hps. You can shop around online for them. HIDHut has them pretty cheap... Home depot is good for tubing and shit like that, but they don't have powerful enough lights for a big space. Also, you should probably go with a 6 inch centrifuge fan. Use insulated ducting, it'll make shit much quieter. Also get an air cooled hood.

oops missed the word cheap... How much money are you looking into spending?

[probably like $250 so.
