Yeah should not be a problem, you can just use a Pipe Fan Connection Reducer 100 mm / 125 mm between the exhaust and filter

Grow tent Temperature
I have a 90cmx90cmx60cm grow tent with a VIPARSPECTRA 300W LED Grow Light inside.. How much will an extraction fan and carbon filter bring down the temp inside? In this heatwave my tent is running at 33 deg C, no plants seeded yet. Will the fan be enough or should I get a cooler?

Temp tent issue
Nice! Thanks guys for the quick help! I’m also kinda sort of having a temp issue, I’m trying to make it the best I can, I’m way down south and the temp reads 86-88 a lot. If I blast the fans and humidifier it does get down but I’m worried about the electric bill going up.

Carbon Filter
Hello growers! I'm thinking of removing carbon filter's outter fabric. It affects my exhaust dramatically. Does anyone knows if this is going to make it insufficient or ruin it? (i think that this layer prevents humidity entering carbon particles)

Risk of bud rot with these conditions?
My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!
