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! ✊😇

Risk of bud rot with these conditions?
My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!

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

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?

Tent heat - needs to go down. Tent gets to 30c when closed.
I want an air intake or something that can cool down an 80x80x180 tent. I don’t have the option to put anything through a window and the air in the room around the tent is pretty warm, so I don’t know if an intake will help. Any advice on what to buy for a small tent?

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.

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 ?

Question about ventilation
I have a 200cm tall tent with a carbon filter connected to an extracter fan/ duct leaving the top corner of my tent. I have no intake air fan connected, although the walls of the tent are bending inward- should I add an intake fan in the bottom of the tent?
