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)

Hey Ho, so far I've been using my 2 small fans at the entrance and the exhaust in the middle. Since there's no air reaching the back and the circulation takes quite a while (smoke lingers for about 1 minute until it's ventilated), I wanted to ask which fan I should install there?

Air-Intake / Equipment question.
Ok, so i bought a air outtake system for my grow tent with a active carbon filter so my whole house doesn't smell like weed as it does now. My question is can i just install my air outtake in there and close the tent without having a air intake ? Or will that cause Problems ?

How do you deal with the humidifier in hydro ?
So I bought a dehumidifier as advised but now the room gets hotter (Had to setup an extractor to pull the hot air and now I have no intraction) and during the day EC goes up of 0.1 or even 0.2 (from 1.8 to 1.9 or 2). I suppose there are more nutriments because of dehumidification

High RH in flower
I find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solution

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?

Won't Oscillate Anymore
I was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.

RH question! Huge veg phase plants
Air humidity increases during night time (up to 90%). I have placed carbon filter below the plants. Question actually is do I need to be too worried if I can get the RH level better within next couple days? It’s first week of 12/12 switch now. :)

Discreet set up
Living in the UK and want to be as discreet as possible for obvious reasons 🚔 Need tips on where I can set up extract and intake without being too visible from the outside and also really quiet fan recommendations? Growing in loft so can get quite warm in the summer months

Cooling whilst using humidifier outside a small grow tent
I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?

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)?
