I have a 4 inch intake fan and a 4 inch carbon filter I was using a 4×2 tent. I just upgraded to a 4×4 actually it's a 2 in 1grow tent however I have the intake fan on the outside of the tent pulling air through the carbon when I put my hand up to the fan I don't feel much air blowing out but before it was in the smaller tent I felt a lot. is this because it's a bigger tent or is it a leak in my ducting system.or do I not have it hooked up properly
