I have a 190 cfm 6 inch panasonic whisper fan hooked on to a 400 watt mh/hps cool tube. Im in the early seedling stage, But want to be prepared for the flowering stage. Where can I buy a cheap carbon filter ? Im worried that my fan wont be enough to cool my room being attached to the carbon filter. Id rather not do a diy. Done enough building this grow room. I just want to order it. Thank you for your help in advance. Maybe I should just move up to the 290 cfm, but then ill have spent like 140 including shipping for nothing on the 190 cfm fan i bought. I see 4 inch scrubbers that are for up to 190 cfm. I could use that and put a reducer on my 6 inch duct?
How much percentage average would you say one of those boughten carbon scrubbers slow down the fan? 50 percent? Someone please answer me. What a helpfull forum this is... JOKEEEEEEEEEEEEE
