your only running a 400 so use a rhino hobby. ther half the length and u are using a small tent so thats best just make sure the filter is rated higher tha the extractor, as that extractor is kinda weak and expesinve you should have a problem
i recomend this as a alternative for your outlethttp://www.ebay.co.uk/itm/Inline-Duct-Plug-6-150mm-Extractor-Hydroponics-Bathroom-Fan-700m3-h-All-Sizes-/390686002408?pt=UK_Baby_Baby_Feeding_Bottle_Warmers_Coolers_LE&var=&hash=item5af6b34ce8
