Привет, друг! 👋 Нет, не выключай вентилятор! CO2 тяжелее воздуха в 1.5 раза! он опуститься вниз, в районе пола и будет у корней, там где ему и нужно быть! 👌 Удачи, бро! ✊😇

Do I really need a exhaust fan ?
If my 2x2 grow tent sits at 26c and 68% humidity without an exhaust fan do I actually need one ? The top of my tent, the vent is open and I’ve opened the observation window at bottom to allow air in. I’ve two fans, one at canopy level and one in top corner opposite the top vent ?

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?

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?

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?

Ventilation Setup for Smell Attenuation
Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

Humidity problems
Can I have some advices on how to lower my humidity? I’m having some troubles lowering it since my plant is now flowering. Usually I can’t lower it from 60% while my temps are always on 27/28 C during lights on. I will leave a pic of my setup here. Should I change something?
