Yay first post. It's my first grow too and I have a few questions about hooking up my lights/ventilation. 6in air-cooled hood and 6in flex ducting. They are both same size so I can't slide the ducting onto the vent to be clamped/taped. I figure I need a connecting piece so I go to home depot and pick up a flex duct connector.....same problem, won't fit inside ducting or vent. How exactly do I attach the ducting? I got my can filter and attached the flange with the included sheet metal screws. I want to mount the vortex fan to the filter but don't know how to secure it. There are no holes in the vortex to allow me to screw em together, and I'm not drilling holes. Do I just tape the hell out of it? I'll also be attaching a silencer to the fan.....and again how do I secure it? Sits nicely on top but I see no way to secure it. Not sure how to attach the ducting to muffler either. Simple questions but I looked and looked and couldn't find an answer. Please help.
