Need a hand with 10ft tall ceilings (Extraction and weight).

Hi guys I'm looking at starting a new grow in a room 11ft x 9ft.

Of this usable space the grow area will be 3.5ft x 9 using 3x600w parabolics which should leave me plenty of room to get around the plants etc. The issue that I have is that the ceilings are about 10ft tall. I have a chimney in this room that I can vent into and conventional wisdom would suggest mounting the carbon filter and fan as high as is reasonable. I have an 8" fan and filter and was looking for some best practice guidance on how exactly to mount this, or whether it needs to be that high up in the first place.

On a secondary issue since the ceilings are so high and because I am going without a tent to secure the fixtures and fittings to is there any "best practice" on how to hang 3 x lamps spanning 9' exactly? I've thought about just running a chain straight across attached to steel eyelets on wood I screw into the wall and then hang the lights from that and also considered trying to source some kind of tent-esque poles with clamps (like scaffolding) in order to build a frame around the area and then hang stuff from that instead...

Thanks in advance for any input.

Make sure that carbon filter doesn't clog up from humidity and start allowing the Plant essence to pass. Parabolics and 600s your in my world bro

Best to have fan/filter as high as possible but with that said if you have a good fan that can completely exchange the air in the room every 3-5 minutes then it isn't that big of a deal because it will pull all the air from the room anyway. You have the right idea on hanging the lights. I would build a frame out of something rigid and hang lights from that. Could use steel, PVC pipe maybe (depending on weight) or even 2x4's.
