5x5x7 tent grow

hey guys, need a bit of advice. I am on my second grow and need to go bigger this time.
I bought a bunch of stuff from attitude to help achieve the weight I am hoping for.

I have the following beans coming in:

Regular:
TGA Subcool The third dimension
Fems:
Barney Farm pineapple chunk
Barney Farm Violator Kush
Dr. Underground King Kong

I will be using a 5x5x7 tent with a 6" 480CFM fan and matching charcoal filter.
My main question is can the tent support a 1k HPS bulb?
I will be using a 6" Horizon Binary air cooled reflector, is this reflector OK or am I better off getting something bigger?
Most likely will do a SOG unless someone has a better idea?

2lb is a realistic goal but even that is 0.9 gpw 3lb is about 1.3gpw and depending on where u are ive got the simlar set up with a 600w cooltube if ur 1000w is open reflector u might struggle with temps depending on ambient temps where u are

update on reflector being used.

SUNLIGHT SUPPLY BLOCKBUSTER 6" is what I'd recommend using a 1000w with.
