Ventilation Setup for Smell Attenuation
MrBz21started grow question 3 years ago
Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

My experience is that you will have a hard time with heat / RH etc as well as there is no room for fresh air replacement. The air coming out of the tent will be a certain humidity and temp. You push it back into the tent and the air will heat up again as you are essentially using the tent as a heat exchanger. And with no fresh air coming in, I'm apt to think that the RH will rise as the same air keeps getting reheated and cooled and reheated etc.
I pull the air through the filter
[Ducting <- fan <- filter <- Tent air] and push it out the ducting. If I weren't drying 2 big ass plants right now, the smell in my basement would be next to nothing even though one tent has 2 more big ass plants starting flower. I've got a this in a 4'x8'x80" tent https://www.amazon.com/gp/product/B084XHGSBT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and it sucks the walls of the tent in just a little bit. and has no smell to it at all.

If you go with a recirculating method you will need to control the temp/humidity/CO2 inside the tent so you will need
1. Temp Control - AC unit and/or Heater depending on the environment outside your tent.
2. Humidity Control - Humidity sensor with attached humidifier and dehumidifier.
3. CO2 - CO2 bags at a min, but either burners or canisters and a sensor.
4. Ensure no leaks are in the grow area( zippers, pinhole from sewing, vent flaps not air tight ) since you have a neutral air pressure it will leak out of any spot it can.
Its much easier to have a passive intake( bottom vent on most tents ) and to have a carbon filter with a fan at the top always on( negative pressure ). As long a the carbon filter is rated for the CFM that the fan does you will not smell anything until the carbon filter needs replacing.

No fresh air intake. it will work but wont be the best you need a constant supply of fresh air recirculating hot spent air is going to cause you some problems :)

How crucial is an exhaust fan and a carbon filter?I cant find anything in my country as a kit, but would buying them piece by piece work?
Example something like in the photo connected to an air duct and then to a carbon filter?
Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

Low humidity issueTents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation
