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! ✊😇

Ventilation on schedule?
If I put my ventilation on an hour on/hour off schedule to raise the RH (RH when cold is around 30%) and help relieve my heaters a little, will it be detrimental to the environment? I've got heaters on controller, Temp is steady with ventilation on but wil be expensive in winter

Temperature trouble
What's the best thing to do ? 1-Open the door of my tent to lower the temperature and lose humidity. 2-Keep the heat at 80F and I keep the humidity in my tent at 70%.

Smell problem
I have a small tent from airontek, not the best in quality with a carbon filter and extractor inside the box, but the smell outside is too strong. When using carbon filter do i have to expect to have (almost) no smell or maybe Im doing some mistakes? The smell is very strong

Is it okay to have the tent exhaust vent into the room the tent is in with an air-con in the room that vents to outside? 2x2 tent in a 6x6 bathroom, air-con sits outside the tent and vents out the widow, door has vent at bottom, is it fine to have tent exhaust into the room? Thx

Humidity Control Tips
What is the best way to control night-time humidity? I have my lights-on conditions pretty fuckin' dialed in, but my lights-off time humidity is around 67-68%. My temps are great at lights-off, around 71-73F. I can put a big dehumidifier in, but I don't want to yet. Any thoughts?

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!

Setup/air quality
So the air surrounding my grow tent isnt ideal. My mom smokes cigarettes inside at night.. so my question.. will it effect my girl, should i have my exhaust and carbon filter scrubbing the air inside the tent and recirculating it back in? Or leave it setup directing air out?

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

ventilation for a 4x8 ? basically is that too much negative pressure and if so should I get anther intake ?
currently using a 200mm inline exhaust fan that has 914 m3/h(537,9 cfm) max currently using it at its medium setting of 792 m3/h(466,15 cfm) and using a 125 mm inline intake fan with only 330 m3/h (194,23 cfm). Should I get anther intake fan or should I put the exhaust to low 680
