New Grower 8' rhino pro? + 8' rvk a1?

[PLANET X]

Hi all.

I'm a noobee to afn and planning my 1st auto grow.

Have 3 questions, hope someone out there can help me.
The grow area is 6ftx6ft. I'm planning on growing big bang autos (600 HPS Sunmaster. Soil).
Is buying an 8' rhino pro carbon filter + an 8' RVK A-1 far too big for my grow area?
Of course "reading the instructions" on the rhino packages in a hydro shop will in a way give me an answer, but that's usually a biased RHINO company opinion. And the webs "needed fresh air exchange per hour" gives me an idea too, but i'd prefer some practical afn feedback on what inch of the rhino+ rvk i should get for my 6x6 ft grow area. Will a 6" rhino and RVK instead of an 8" set up suffice?
So far i've learnt that it's best to have them bigger than i need due to them having more cooling power in the summer (I live in barcelona) and also because it'll save me having to upgrade both should i want to enlarge to any bigger future grows.
The only down side is that the bigger the rhino and RVK , the bigger the noise is going to be, and i can't be having them loud ( even with acoustic ducting to help)
2nd question. Can one just position a fan so that it blows cool air on the bulb and reflector canopy of my 600 HPS? Could that work as well as a "cool-tube set-up?
And finally, my head is spinning with too much info (Good that it all is i'm sure). But i still can't decide how many big bang autos i should place under my 600 HPS sunmaster. Some say 9, but other growers say 50 watts per plant (Which means 12) and a few say 18, and one chap says 20 (!?)
Hope i get some answers coz i'm buying the rhino in a week.
Thank you all.

H'mm, 4 plants!? I'll bare that in mind. Thanks. Though i'll make up my mind on how many i'm gonna plant, on the day.

RVK? is the fan that comes with the rhino filter. You can google it to get more info as i'm just a noobee.

Thanks again.

Btw its 50 wats per square foot not per plant as one plant can be 1 - 6 foot tall and or wide. Normaly autos are between 1-4 feet tall and about 1- 2.5 foot wide unless trained diferent. But unlesw u got Huge space u should put as many plants.as ur space can handle not by what u think is right for your light. Its better to have to few than to many as the light will be.blocked from other plants. Unless u were doin a photo grow and flowering from seed or clone with no veg then u could do a sog and have 20-30 easily of course these r all roughly as it is all strain dependant.

I missed where u said it was a 6 x 6 area i would use 16 for that space but i would not use all that room with only 600 watts u will get loose buds. A 600 watt is only good for a max 4x4 if u want good dense buds and u will need a huge hood for that 600 watter to effectively cover that area.

Been heavily web- surfing since i started this thread-question (Should have done that first)
You're right. Seems it's either a few big plants you get with a 600hps, or a lot of small ones.
From now on i'm gonna web-surf-search any future questions i have and only pop a thread-question onto afn
when the heavy web/afn surf-search fails me.
I now know the answers to my other 2 questions having just done this.

Seems "the knowledge" is all out there, (and and of course across the AFN!).

Nonetheless,thanks for your info and patience archiclife.
