I'm having similar issue I had my scrubber and hood on same fan and ducting. Was worried about carbon dust and crap blowing over my light. So after I've decided not to do this. I only have one exhaust port going out the room. Can I put scrubber and fan connected to a Y with a separate fan and duct for my hood. More simply put can I exhaust scrubber duct and hood duct out the same hole? Any info would be big help! Thanks
