Entering the 7th week of flower and these ladies are smelling wonderful, and that’s the problem. I noticed yest while walking down the hall that the smell is coming out of the tent and into the room, then the rest of the house. Have a vivosun carbon filter and 6in vivosun exhaust fan. The exit path is kinda long so I thought maybe that’s the cause of no negative pressure in tent. But after smelling the smell I walked into the room (during dark period) I have so many needle holes in my hose duct work that I’m now 100% sure this is my problem. I’m probably losing 30-40% power due to all the holes. My question is what is the best exhaust hose to use. I bought the flexable and isn’t holding up. Need it to hold up so I’m not having the sMell leak out into my house and need it to create negative pressure again. TIA
It’s best to have a viable speed on the exhaust fan so you can adjust it to where you have adequate amount of negative pressure. You want to see those walls sucked in. I have never had any problem with the flex hose that comes with the fans. I’m sure you could replace it at your local Lowe’s ,Home Depot, Tractor Supply. Good luck
Are you pushing the air through the filter or pulling it through? I.E. is the filter on the intake side of the fan or the exhaust side
Pulling it, carbon filter>exhaust fan(with speed control turned on High)> exhaust hose out the window. Tent is a 2x4x6 … I’ll try to snap a pic real quick with flash on of the distance outside. Since I’m in dark period atm. I’ll take a pic of the inside when lights come on
I’d question your filter functionality then. After it passes through the filter, there should be no odor
If you have no negative pressure you could possibly have a filter pluged up.
I’ve also wondered if the length of the exit hose is too long(as in I need another fan at the end to help pull it the length of the hose and out. Especially with all the holes causing a loss in the pulling power. Also I wonder if it’s such a positive pressure inside that the air/smell is being pushed out anyway possible and that is leaking out into the room.
First pic is of said holes. I can only assume they are everywhere in this hose. Even attached to filter/fan
I would remove the filter from the exhaust fan turn it back on and see if you have negative pressure at that point if so you have a plug filter.
Boobydigital has you covered. You could have an exhaust hose that’s Swiss cheese, but if your carbon filter isn’t working, holes have nothing to do with the smell.
UNLESS you have holes on the intake side…
A little bud porn for all who dropped in to help and give suggestions. This is the lovely lady im trying to give a comfy home. Greatly appreciate it and have learned so much from everyone in the community. This is my 1st grow and she wouldn’t be as lovely as she is if it wasn’t for yall. Thanks
What strain? My amnesia has those same yellowish pistils

Yeah, somethings up. Agree with @kellydans that you should unhook the filter and see if the tent sucks in the sides like a woman on her wedding day. There’s no reason that tent shouldn’t have negative pressure with a 6” fan unless you have a lot of bottom ports open.
Only one and that’s where the ac blows in. I’ve backed it up from the opening and it seems to be helping. Maybe too much intake from ac? Heat wave so I had it close to keep the tent at 79. 
it’s still not sucking a watermelon thru a garden hose tho
Managing the temperature in the room outside tent is the best way to control a temperature inside tent. I don’t use any intake fan. I crank my exhaust fan up to about medium open two pass through holes at the bottom. At that point I’m pulling fresh air in at the bottom. And exhausting out the top. I have never had a mold or Bud rot issue inside tent. Outside Garden is a different story. I think you got it figured out you putting more in than you’re pulling out .good luck
