You should run ducting that is large enough to support the cfm your particular set up is going to require. With that being said the larger components cost more money. I'm a fan of saving money so if that means your system requires a cfm that can be facilitated by a 4 in fan then I would go 4 in and adapt to the hood. Same goes for if it requires 6 in. But price it out completely all different ways and weigh your options and pick what feels best.Hey Newbie, do you know if...... my hood ports are 8" then all my ducting should be 8" and do I run an 8" fan? Or can I run 6' duct and fan with adapters/duct tape at the 8"hoods?
