Doubling up pc fans?

Hi there everyone I am a first time poster but have been doing loads of research here for sometime now. My question is.

I have a 2' x 2' x 4' homemade stealth grow box. I have a passive intake and a 5" hole on the side near the top to vent my exhaust for my homemade carbon filter. Heat Is not really an issue because I have a plexi glass shelf dividing my lights from my grow space that has it's own ventalation. The fan I am using to push through my carbon filter is a 120mm, 130 cfm fan that is thicker than most and is designed for static pressure. However I don't feel it is moving enough air through my grow area. Would it be possible to just get another fan and simply double them up? Have 2 fans attached to each other both blowing out? Will that essentially make it seem like there is more pressure to push through the carbon filter? Or would the fans just cancel each other out?


Please and thanks for your response.

I have been thinking about something like this myself. My cab is about the same size as yours and I am looking for exhaust that wont ruin the stealth of it. what is the brand and model of your fan?

I have this fan here.

thanks. Id be interested in seeing your setup. The plexiglass is a good idea and something I would like to look more into. you should start a journal to show off. I am thinking about picking this fan up. http://www.lowes.com/pd_185009-1061-DB206_4294933130+4294836901_4294933768?catalogId=10051&productId=3089845&Ne=4294933768&currentURL=/pl_22_4294933130+4294836901_4294933768_&N=4294933130+4294836901&identifier=22&langId=-1&storeId=10151&ddkey=http:CategoryDisplay

The best fans for a stealth grow are these fans. They have no motor and run by creating a magnetic field or "magnetic bearing". Thus you never have any motor noise, just the wind. as quiet as your can get.

pc fans just dont do static pressure but for stacking them seems to help i got a 21" by 12" cab with a 150 hps with sqaure homemade light traps with 92mm pc fans added 3 26 cfls temps went 95added more 92's on other side of light trap temps went down to 88 added 2nd exhaust trap now at 82 which is bout 8 above ambient but i tried the thin little filters and temps sky rocketed im all for diy keeping it cheap you can sucessfully cool with pc fans and be stealth cause im rocking 12000 lumens ina bout 3 c ft box no prob but if you wanna filter yer gonna need a can fan or maybe a bathroom fan from lowes
