This has got to be a joke honestly. I'm not trying to be a jerk, I'm all for helping out noobs, but you don't just decide to set up a 6k watt room for your first indoor grow.
My suggestion would be to build your space, and buy 1-2 1k lights. The super suns are ok, I've got my 1k in a great white reflector and it covers a 4x4 tray nicely. I personally would look around at some people journals and try to plan a room similar to the ones you see being success full. Are you wanting to go hydro or soil? This is a great thread that spells out step by step alot about growing, and explains EXACTLY how to build a room that will get you
https://www.rollitup.org/hydroponic...eeks.html?highlight=harvest+pound+every+weeks . There are lots of ways to grow, and lots of ways to build a good room. You need to start by READING READING and then READING some more to dig into the information. Then start building once you figure out a plan that will actually work for you. There is grow gear all over craigslist from people that thought they would just "grow some weed" and realized they got in over their heads. If your not paying for this all yourself your investor prolly wouldn't be very happy if you built a 6k watt room then had 1 or more failed grows for any number of reasons.
