The credit for this design goes to TeriYaki and his complete box info https://www.icmag.com/ic/showthread.php?t=247695 is there any advantage to the space between the carbon filter and the fan? he has a piece of pvc pipe inbeetween the fan and filter Would it not be just as effective to make a square of carbon filter on the fan would it be more effective to have a fan on both sides of the filter with a carbon filter squashed between similar to his design or would it the air move too quickly and not be filtered? thoughts?
yes it might work. try it with 1 fan first and if its not enough try 2, also try altering the voltage so it goes slower or quicker you might need to replace the carbon at some stage
i was planning on replacing the carbon every other grow or between every grow im growing in a pc that is 26.5x18.5x8.1 inches so its not much space
