Air Flow on GrowRoom

Thread starter #1
Hey guys, i might need your help on this one. I am using a grow tent inside a bathroom, which has no windows nor has any sort of external ventilation. I need to find a way to create an air-intake for my tent, but always considering i must keep my room closed at all time. Extraction isint a problem, but i dont want to intake the same air thats being extracted. I've been thinking on using an air purifier for the bathroom in order to deminish oxygen levels. However, im still struggling with co2 level within the room.

Any suggestions and thoughts are appreciated. Thanks!!
