started grow question 5y ago
So, the title is pretty straightfoward. I was thinkin about getting some 127mm extraction tubes and make it really tight to fit the filter. TIA

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

Maintaining VPD
I've got my photoperiod doing well in a 2x2 tent. I'm trying to regulate my VPD with what I have on hand. Currently I'm running my exhaust fan for 8 minutes every hour to get an average VPD around 1, but I'm concerned about the swings. Am I micromanaging?

Can I close the door of my closet?
My tent is located in a closet kind of room (5x2 meters) and I was wondering if could close the door during the night because the fan is a bit noisy. Will it fill the room with exhaust air/humidity and damage everything inside (the plant, also the clothes that are in the room)?

Setup/air quality
So the air surrounding my grow tent isnt ideal. My mom smokes cigarettes inside at night.. so my question.. will it effect my girl, should i have my exhaust and carbon filter scrubbing the air inside the tent and recirculating it back in? Or leave it setup directing air out?

Air flow method
I removed the hood from the home AC to run cold air directly into the grow tent with a 4 inch duct at the bottom. I have an inline fan to push hot air out to balance out the air pressure at the top. Is this a good idea or should I just have a fan inside with no in or out?

Speed of outgoing TD Silent
Do you adjust the ventilator speed over time? I have a TD Silent with 5 possible speeds and keep the lowest speed at night (so I can sleep) and on 3 or 4 during day to be sure. Is there a trick to find the best yet lowest speed?

Using humidistat to control fan, will this cause problems? So far fan running for 30 secs every two minutes! Plz advise if this is not a good idea??
My exhaust fan is to powerful no speed control just two settings. On the lowest setting the fan is still sucking all the humidity that my humidifier creates out of the tent. So I have bought a humidity controller hooked it up with the humidifier and fan.. It’s working great!!

Can a carbon filter be too "big" for an exhaust duct fan?
Is it fine to use a carbon filter that can handle twice the capacity of the airflow my fan can produce? Or will the fan have trouble ventilating the tent then?

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Slowing a two speed inline fan
Can I run a fan speed controller with a dual speed inline fan? My 4” two speed fan is slightly too powerful for my grow room. I’d like to slow the fan slightly but I have heard the these types of controllers don’t work with two speed fans? Any advice or what to buy to do the job?
