Being new to all this i would just like to say Thank You for all the info i've got so far, my next question is I'm growing 3 plants in a space of 130 x 100 x 46cm, I have a 75cm tall oscilating tower fan that seems to be doing the job. But a read about these extracter fans that take air/heat out of the growing space and put fresh air from the outside in to the grow area. would i really need one or even two of these fans in such a small grow area with 3 plants ?

Depends on your lighting, what you using? What are your temps/humidity? The more air flow in your grow space the better imo.

Only using a 125w Envirolight and temp rarely goes over 81f, Just read alot about these extractor fans, maybe it will be o.k, if not i'll have to think about getting one ! Cheers for replying

Seeing as your not using a HID light and your temps are not getting too high i reckon you could just use a computer fan exhaust up top and a passive intake down the bottom. Just to get air fresh air/co2 moving through. Or as a previous poster said just leave the door open crack, only downside too that is your losing light that could be potentially reflected back to your plant. Good luck.
