This is my grow hack to stop contamination and light passing through my intakes. Just a 1 gallon grow bag over a 4 inch pipe. At first there was also carbon mesh sheet filter under the bag to insure proper filtering however I have gone to only the bag due to this only being for insect protection and light blocking as both of my tents are in my bedroom. After testing countless ways over the years this allows for maximum airflow and almost no light to pass threw also Cheap and extremely simple.
