Hey I recently updated my grow tent recently. Splitting it into two rooms a flower & veg room.. the flower room has a big fan in there & one air vent open... I think this is mold but I’m not quite sure. I had thirps recently but I got rid of them. I just want someone to confirm is this mold or mildew & if I leave half of my tent open during the day will that be enough ventilation for the plants?
