Hey All, Thank you for this site and all the knowledge to be found within. I have a 25cf tent, with a 300 watt LED (185 true watts) I was looking at a 4" inline fan (170 cfm) which I was going to get a filter with similar cfm (200) I was planning on hooking that to a variable speed controller, which I would plan on using at about half speed, I guess. Question, Should I match the filter directly by cfm (with the fan) or at the cfm at which (I think) I'll be running the fan? Would the similar filter to the fan still function properly at the speed? Any help or suggestions would be greatly appreciated. Thanks again.
