The reason for extraction question

[Thebanktella]

another question guys I know the reason for extraction is so ur plants dnt burn or over heat from the lights giving off heat, but if I'm using cfls and a fan in the closet is there another reason why i need to have an extraction thang going in my stealth grow ? I know u must have one , but not sure the main reason Sorry if it's a stupid question but it's been bugging me for a bit

Humidity

Humidity

I take it that's due to the watering of the plants and heat from the lights?

And when lights are off.
Plus its good to change the air in the room also.

Im not sure if YOU need one but I built out a closet for clones and small veg plants.
Mine is pretty airtight. So i need the vent

Extraction is also needed for odor control in a stealth setup. Carbon filters are required to scrub the smell out off the air. If you're running sealed you still might want an internal/circulation scrubber

All of the above. Humidity control, odor control, but most importantly to keep fresh air cycling through the space as @charface mentioned. Plants need fresh air just like people. Don't give a human fresh air and eventually they will use up all the oxygen and die. Plants will do the same with Co2.
