Setting up my grow room, need advice

The room im working with is 6x5 ft, i have (2) 150w hps lights and (1) 400w mh right now should that be enough light for the whole room?

What are some ways to help with smell? (Its not a stealth grow but i dont want the whole apartment reeking)

venting and alot of people swear by carbon filters store bought or homemade

6x5 what? feet or meters?

feet, sorry

IMO ... I would rather use two seperate bulbs for each task:
2x 400w HPS for bloom
2x 400w MH for veg
The canopy will be more even and you'll get more bud for the buck.
But if you have the cooling and the $ I would go for 600w bulbs

I'm currently using 1x600w HPS in a 4'x3' cabinet.
