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! ✊😇

High humidity in the morning
I’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?

Temp tent issue
Nice! Thanks guys for the quick help! I’m also kinda sort of having a temp issue, I’m trying to make it the best I can, I’m way down south and the temp reads 86-88 a lot. If I blast the fans and humidifier it does get down but I’m worried about the electric bill going up.
