S&P or Can for my setup.

Got a mothers keeper tent from HTG. Going to order a phresh filter 4" air scrubber. Just not sure if I should go with the Can 120 cfm, Can ho 155 cfm, or the S&P 4". The S&P seems like it would be nice because they are suppose to be so quiet and the design seems as though it may save me some precious space considering I have a smaller space with the tent that I have. Plus I believe the cfm is only 97. Noise is an issue but would 97 cfm be ok for that tent? Btw I have a Sunblaze 4' x 4 lamp fixture. Any advise or other ideas?

your not providing enough info for me to answer your questions.....how big is your grow room? also its not the filter thats loud its the fan. the more things you attach to the fan the quieter it gets.......you want the CFM's of the filter to be bigger than the CF of your grow room and also bigger than the CFM's of your fan. i always use phresh because they last the longest and use Australian carbon.

I know its the fan that makes noise. Filters just sit there and pull air through them first. If you are not familiar with the mothers keeper tent from HTG then the dimensions are 51w x 48h x 22d. Think the scrubber was the 4 x 12 phresh filter with 200 cfm.

So would 97 cfm be ok for this set up? Oh I think they also, s&p that is, sells a higher cfm version too. Think it may be 140 cfm but would I need that much?
