i have a four inch hole in my grow box, would putting a four and 1/2 inch fan begind it for exhaust be a problem?
inside the box for stealth or outside the box if you're tight on space. it won;t make a difference in airflow if you seal it well enough. if you have problems with the seal you should put the fan insidealright thanks, Mr Marks- btw my jigsaw is broke which im fine with because i've built everything i just need a hole, and the hole saw will be perfect
another question should i attach the fan on the inside of the box(so it would be pushing the air outside) or should attach it on the outside so it's sucking the air out
