im gonna try to vent out of my house but if it doesnt seem to work because its winter amd dont want to look weird having a window open but any advice for having it vented inside or pros and cons between the 2
Venting does 3 things, it removes the heat and with it the humidity and exchanges the air taking away the co2 diminished air and bringing in new air with higher co2 levels.
With a small grow not venting out is possible, humidity can be lowered with a dehumidifier , though it might be one is not needed, co2 in your apartment will be fine since you live and breath in there, smell however can build up in some cases due to the same air getting recycled.
A good filter will take care of most of it. There's always ways and means... Some folks run a separate stand alaone scrubber.
