Cabinet ventilation question

Please bear with me I'm an extreme noob. As a matter of fact I'm still trying to plan how to build my grow cabinet for my 1st time.

Thanks to all for so much information already. I feel like my head is spinning from all the reading and learning so far.

So I'm building a small office in the basement and custom building a grow cab. My ideal size will be 3' deep by 4' wide and up to the ceiling (just under 8') but it isn't set in stone.

The picture included shows the clone area on top at about 18" the veg/flower area on the bottom at about 5' and a middle space at about 8-10"

I'm assuming in a small area like this heat will be an issue without an air cooled tube/hood so I plan on using that with a hps 600 bulb. I also would like to vent through the middle compartment and then come out thru the floor of the clone area, and out the top on the other side of the chamber.

Thinking about how to do this has got me slightly bugged out on losing a ton of space with all the separate vent hoses and a zillion fans (I already planned on having an intake fan and a good exhaust fan but now it seems I need to add 2 more fans with the cool tube thing. I already figure there's no way around another intake fan for the air cooled hood, but has anyone tried to use one powerful fan (I was thinking maybe an 8" inline) to exhaust the cool tube and the grow space by attaching some kind of splitter so both can exit thru the same exhaust fan.

I hope this makes sense. If not, tell me I f'd up on explaining and I'll try again.

I forgot to mention that I'm definitely going for stealth on this so that means I'm trying for everything inside the box

Flip your design upside down and have the flower cab on top. Connect the fan to the end of the cooltube and just suck air through that. Don't have a separate veg clone area just combine them and put a passive air intake in the bottom or side of that. Then add ducting from the veg area to the flower area and snake the ducting so its light proof. Its probably hard to understand through words but let me know if you got it? You're other option is to just use an inline fan for the flower area and use something like computer fans for veg.

Thank you both for the responses. I can't believe I didn't think of that! I feel like a real dumbass now! As far as the passive intake goes, I don't mind the extra fan. If it's better not to have it then great, but I keep hearing having one is king. I was more worried about all the ducting getting in the way.

Anyway, you guys rock. I just wish I had thought of that very simple solution.
 
I dont know if its just me but a 600W seems like a very large light for that amount of space. I have a 600 in my room and it is alot larger than yours and i have a intake and exhaust fans present and I still have to tweak stuff because of temps. 7

only Stealthy can grow with a 600W in a cab :P .You can find his multiple journals somewhere on here, he is the stealth pro and he can give you a bunch of advice. hehe it's totally doable, but 400W for a first run might make things a lot easier, and IMO will barely affect your harvest.
