Hi Ford. That will stop the duct run at the ceiling hole. I want duct to run through the ceiling and connect to extraction fan in the ceiling. Other suggestions above, like ceiling grill, also all stop duct run at the hole. Only thing I can think of is to get 200mm circular ceiling grill and cut the middle out with a Dremel (diameter of 150mm insulated duct is thicker than 150mm) Sent from my SM-N970F using Tapatalk

Hi. I'm trying find out the neatest way to run 150mm insulated duct from my room through the ceiling to exhaust into roof. I was planning on moving my extraction fan up into the ceiling and run duct down into my grow tent. This will solve two things, get rid of hot air from the room and reduce audible noise from extraction fan. I wanted something neater than just cutting a hole in ceiling plaster board. There must be some sort of flange / port hole type of fitting? Any ideas? Sent from my SM-N970F using Tapatalk

Hi. I duct taped Dynabreeze Filtamat over the mesh vents. Keeps dust and bugs out and some light out. I plan to tape another layer over the one I already put on to stop more light. It can be cut to size easy. It's from Bunnings for about $30. Sent from my SM-N970F using Tapatalk

Hi, I have no experience in this but would vinegar spray not help kill mould.
