is this enough intake?

[J.cun.Shallow]

I have a 4inch intake and a 8 inch outake im worried that the intake is not enough. I have just got myself one of these http://www.progrow.co.uk/acatalog/info_4925.html

I dont know the size of the room of the top of my head but I do know that the 8inch is big enough for the room

We need more details, like are the "intakes" and "exhausts" passive or active. And is there filtering involved, or is this a strait ventilation system?

These details would help. However, generally the outtake/exhaust is greater than the intake by 3-4x (iirc) to keep a negative pressure within the grow space. This is important especially with filtered setups because it ensures that a minimal (ideally zero) amount of air is being exhausted without being treated by your filtration.

What kind of fan, and the specs. some 4 inch fans are more powerful than others.

thanks for the replys ppl

I have had the 4inch inline fan for years so dont have the spec, but im fairly sure its a vk -100 inline fan 250 m3/h and the outake is new it is RK200m 765m3/h
there is only a pair of stockings covering the intake so the flow isnt really restricted, and yes I have a carbon filter so the outake will be restricted, but the room is not sealed there is just a few gaps around the door.

I'm probably just worrying about my babys to much agian. but like they say, if a jobs worth doing its worth doing properly

That sounds like a fine set up
