Thanks to everyone who replied. Went to home depot yesterday and picked up...

-4 23W 1600 lumens (those, plus the 65W/2k lumens i have should be enough for 3 plants, right?)
-two Y sockets with extension, etc....
-3 5 gallon buckets

So at the moment my lighting adds up to 8400 lumens.

Minor set back...my buddy is considering backing out on my grow space, but I have other friends who are interested.

Heres another question for you guys. My buddy is considering backing out because he is worried about the smell the plants produce once they flower(which is very potent i know). What are your opinions on how to reduce smell? I read on here that half a box of baking soda on a plate could help reduce the smell, but I havent heard from anyone who has actually tried it...therefore im not willing to say that it works yet.

I looked up some filters/fans and the few i looked at were 100$+...are there any cheaper methods that work well? I'd be interested in anything you guys throw out there (hopefully with factual experience).

Thanks again to everyone who has been replying and supplying me with valuable input, it's very helpful.
