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

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!

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?

How do I know my filter is still running ok? can it wear off in just a month?
I have a vulcan carbon filter for a tiny tent. It runs 24hrs a day for the last month. Now, the smell coming out of it is not neutral anymore (not strong cannabis), but it is a bit heavy and I'm getting paranoid. How do I know my filter still runs fine? High umidity is a factor?

High humidity in the morning
I’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)

High heat in greenhouse, how hot is to hot?
I built a 16x20 greenhouse with dual vents and a 24” exhaust fan. I hit a max of 122 (it’s 92 outside). I typically reach 105-110 on regular days. Everyone looks happy other than an nutrient burn issue. Can weed plants handle this kinda heat?

Do any body have any experience in making your own carbon filter?
Thinking about making one from two steel mesh "ovals" with +-2cm in between. Use some filtration cloth so the carbon don't go through the mesh. And will fill the space between the meshes with activated carbon used for this purpose. Do you think its going to work? Thanks
