Thanks for the reply crisis but i think you're missing my point.

In my diagram the upper section will be seperate from the growroom and sealed airtight. I wanted to keep fan and carbon filter in here. For this i would need the carbon filter inline as the diagram shows.

I am yet to see a set up like this and i can only presume that it can't be done as the air needs to be pulled through the 'sides' of the filter instead of through the end like i would need it to.

anyone?
tripleblack Reviewed by tripleblack on . Would this setup work? I thought it would be nice to seal the upper part and keep fan/ducting in there but I'm not sure on the ducting and do 'Inline' carbon filters actually exist? Either two passive inlets would have ability to close off so in cold weather air could come from just the house and not outside. New to this, any help appreciated. TB P.S NOT to scale! The GR is certainly not nearly as big as the house, in fact it is only to hold 3 plants! Rating: 5
