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! ✊😇

How crucial is an exhaust fan and a carbon filter?
I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

Humedad dentro del cultivo
La humedad está llegando dentro de mi cultivo al 80% y hasta el 90%, he comprado un reductor de humedad que venden en el supermercado de estos que reducen la humedad y llevan unas piedras adentro. Esto le hará daño a las plantas??

Additional environment control
Options for extra humidity and temperature control. Continuous drain not a problem. My Rh can stay in the 80% range for weeks. Attempting to control a 10x10. Would a small window Ac remove enough humidity (easiest)? Portable AC/Dehumidifier? Stand-alone dehumidifier? Suggestions?

Carbon Filter smaller than Fan
Is it bad if the Fan makes 200m3 but the Carbon Filter is only for 100m3? Do I need to change it as quickly as possible? (Tent 60x60x160)

Ventilators OFF/ON
Hi, guys. I have one more question today: - My box has three ventilators. One is working in the upper air channel all the time to bring out hot air. Other two staring on my plants. Should I use all three of them? Or one is enough till my babies will grow thick to pervent mould?

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

Help with airflow. I've got an extractor and 3 circulating fans. Would a powerful inline fan be better than the 3 circulating fans
Question about environment here. I've got a 5x5 tent. Total 46m area. 460m3/hr needed to be extracted. Extractor fan is capable of taking 600m3/hr. I did have in an inline fan but it's no longer working. Do I need another inline fan ?? I've opened two ports for passive intake

How to reduce humidity in my grow space?
I'm just an amateur and am growing in my closet as I have very limited space. It's a small space in which I can't cut holes or openings. I use a small fan and a air purifier. Should I get more fans? Does a carbon filter or inline duct help if it can't exit out of the closet?

High humidity
Hello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.
