How do i get rid of 100% of the smell during flowering

Hello, i am about to start my first grow but i need some help regarding the smell.

I have a 40 x 40 x 120 cm tent that is paired with a 150 m³/h fan and a 240 m³/h carbon filter.
Will i be able to vent out through my window or will my neighbours catch a whiff when they go out to their balcony (aprox. 10 meters from my window)?

It all depends on the quality of the carbon filter.

It's a pretty cheap filter, i paid €40 for it.
Fan speed will be set at almost half of what the filter is rated for (fan set to 150m³/h and corbon filter is rated at 250m³/h)

Exhaust outside. Keep a spare filter handy. Most importantly, never open the tent.

You can always add a second carbon filter. One inside the tent and one outside.

The issue with cheap filters is mostly down to poor packing, if they leave air gaps in there from lack of vibrating it down then you have a space for smell to pass through without proper contact to carbon.
That's all it takes to have a smell problem.

Buy a quality brand filter.

When its working properly a filter will remove the smell and you can vent it outside without worry.

Any odour that your cheaper filter didn't scrub during exhaust should dissipate in that ~33 feet between you and your neighbors. But the more pressing question ... have you pissed them off recently?

Generally one exhaust filter is not adequate when you hit peak stench. The addition of a second filter and fan combo as a scrubber, recirculating air in the tent, is the solution. this means the exhaust filter only has to pickup the slack. If you have enough scrubbing then you won't smell the weed standing right in front of it in the room. A quality filter like a Phat filter running to process the volume of your tent 2x a minute will eliminate odor. You can setup the scrubber so that it circulates air from the bottom to the top of the tent with a stick of duct, this will avoid blasting the plants and provide even temperatures throughout the tent.

When you're paranoid like me you can also put a 4L Ona tub in room just not in the tent and works fine

For sure. I think that's why he mentioned not in the tent. I still don't think it's good to have in the intake air though.

If it's in the tent more than probably yes but the room no, been doing it years and zero issues ever.
