4x8x7 tent.
6” exhaust fan 420cfm (yes really 420 lolz)
3 oscillating fans inside
Dwc
(2) 315w cmh

Smell is bad. Swapped filters. Smell is still bad. Outside the tent.

So I added another 6” 420 cfm exhaust fan but put it intake side. Ended up ballooning my tent so I turned it to low and it’s fine now. It’s connected by 25’ of insulated hose.

Why does it smell so bad now. 4x4 tents never smelled outside tent. Why is 4x8 stanking

Inside tent temps 80f/65rh

Dehumidifier is in same room with tent set at 50rh. Getting free ro water from the dehumidifier lol

All joking aside help or I gotta bail-ski

Are you outrunning the filter? Check the filters ratings for CFM and make sure you don't exceed that or it won't have enough exposure time to clean the air. You may need a scrubber in the tent, a filter that simple recycles tent air. I run scrubbers in my rooms and you can hardly smell the weed when standing next to it, turn the scrubbers off and you can smell it at the street within an hour. So if you scrub the air and only vent enough to cool the tent it may control your odor. By pushing more air through the tent you are only outrunning the carbon filter and making the problem worse.

Stop using the intake blower, make it into a scrubber with a carbon filter and run it in the tent. If you have a speed control reduce the exhaust fan speed as much as you can without suffering high temps, that will increase exposure time for the carbon filter.

With a LED you actually need warmer temps due to the leaf surface temps and the general lack of infrared. Usually with LED you want to run around 85 degree canopy temps and some actually have to add heat in the winter if their tent is in a cool basement.

Not looking to change lighting. Cmh is amazing for quality. Leds didn’t. Sell me.

You think I just need to run 2 filters and 2 exhaust fans or just slow down my exhaust fan?

Slow the fan filtering air. Even better is putting a 4” fan on a 6” filter. The decrease in velocity increases the air pressure on the walls of the carbon filter and allows more time for odor absorption. Neck the exhaust back down to 4” to maintain this pressure.

So when I use the 6” as an intake it balloons the tent. I think that’s a bad thing. So should I just keep 6” exhaust turned down maybe on L or Medium fan speed setting and do passive intake or should I double up do 2 exhaust with filters? Because one alone wasn’t cutting it. Can’t seem to get under 65rh. I have a dehumidifier running 24 hour it’s in same room as tent. When I had it inside tent the temps stayed at 80f and rh would stay low 60 sometimes 50. Thought the intake blowing in would help but maybe that ballooning the tent is pushing air out of tent and overpowering the scrubber. So I’m trying anything. Going to try the 8” scrubber on a 6” fan to see if that helps like previously stated on here but need some ideas for right now. Should I put the dehuey back inside the tent to keep rh down? Thanks for all the advice so far.

The 6”>8”>6” will help with the odor. Especially if you can bring the RH down a bit more.

^^ thought so. Damnit. I was just trying to have it blow through top of tent so it would help push hot air around cmh hoods out the carbon filter on other end of tent. Shit. No wonder my shit smells like a skunk orgy.

Reading up on Venturi now. Would a bandaid fix be runnin two carbon filters and two 6” fans connected to them for now? A little low on $$ right now to buy another $100 filter

So as of right now should I toss the dehumidifier in the tent to keep temps 80f/55rh. Or keep it in same room as tent to keep temps 77f/65-70rh. I’m going to hook up two 6” exhaust fans with two scrubbers. As a bandaid fix for stank

If the stinky air is a few degree warmer than ambient, then you could open a window and keep it from coming down the stairs. Furthermore, trying lowering your thermostat a degree or two. That causes more warm air to go up the stairs. You have AC in your tent room, right?

Hope this helps.
