Hey, buddy! 👋 No, don't turn off the fan! CO2 is 1.5 times heavier than air! It will settle down near the floor and be at the roots, where it needs to be! 👌 Good luck, bro! ✊😇

Set Up Tent
How should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?

Ventilation question
Is it possible for me to take down the walls of my tent and leave the frame with the lights on it to let the plants get more space? I don’t have a way to ventilate the entire closet from an external source, just been ventilating the tent w/ an exhaust fan and carbon filter

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. :)

Temps in Flower with Co2?
Shall I keep 29C as my temps (which is said to be ideal for Co2-enhanced grows) or slowly decrease (simulating autumn)?

Circulation / Exhaust
Getting ready to install carbon filter; found myself wondering if growers typically leave their filters/exhaust/fans on during dark periods? Up to this point, I've had everything on one power-strip/timer: circulation fan, exhaust fans, and lights. Should I keep anything on 24/7?

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

I made a firebomb?
Is it a fire hazard if 5v computer fan is jammed and the power is on for 2-3 weeks? I'm far away from home and I have camera in my growbox. A tape has fallen to the fan and it is not rotating. Can it heat up so much that fire starts? Should I drive 1600km for that?

Exhausting air outside when using Air Conditioning, yes or no?
Hi there. This is my first indoor grow in soil. I have a room with A/C. The grow tent is in that room. My question is, should I be exhausting the air from the tent outside or into the room. If i exahust the air outside, isn't it counter productive to the A/C?

Can I exhaust my grow tent into the closet it's in?
I'm putting a 3x3 grow tent into a larger closet I have (maybe 8' x 4')? So I guess the closet is called the lung room? I will have a carbon filter and inline fan in the grow tent exhausting out. Can I exhaust out into the closet it's in? Or is that a no-no? Pros and Cons?

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

Temps to high....i think
Hi, newbie here, I'm really struggling to keep temps below 30°C. Outside temps are not helping all, i have my extractor on full, air circulation fan on full, both flaps open, shed door even open lol and my light is turned down to 250 watts, which probably isn't high enough!

Do you think this is a better position for carbon filter so it can have better airflow or is it more important to scrub air from the top and have 2 90 degree bends? I'll probably try this in my next grow. Pic with drying plants is setup from before with 2 90 degree bends.

Odour control
First indoor grow and is a stealth grow. I’m wondering if complete odour control is possible for one plant. One auto in the tent with a large carbon filter and appropriately size duct fan, walls are sucked in — I also have ona blocks to place around room during flower.

Trouble keeping my RH below 65% in grow tent (I water once per 24hrs, 20% runoff)
Hello fellow growers! I am having trouble keeping my RH lower than 65%. Any ideas (without using a dehumidifier)? For extraction, I have a RAM mixed flow with a passive intake. It seems for the space (0.8mx0.8m), that this is more than enough. Any help is appreciated. Thanks!
