Do I really need a exhaust fan ?
SneakyDogstarted grow question 5y ago
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 ?

always have an exhaust fan and always have it on. that's because it will help with mold and contaminants. it's pretty important.

As DasBoof said, you can and will get mold. I just had mine not turning on and now I'm battling WPM. You need extraction to bring in new air.

You current situation would allow a fan with minimal use, while
providing fresh Co2 for your plants. Allowing to control order as well if you choose to filter it as well. I have been using 2, 4 inch smart controllers fans and they have been great for temp and humidity. Is a good setup. Good luck and happy growing 🌱

Exhaust fan are still usfull even if your not using it for temps, you can add a carbon filter to control the smell and it also renews the air in the tent so the plant has fresh c02

Carbon filter sleeve needed?I use the carbon filter on the exhaust side. On the intake side, I have a dust screen mesh.
The tent is quite clean so that’s why I don’t see the need of the pre filter. Would also probably load the inline fan a bit too.
What’s you thought?

Humidity Control TipsWhat 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?

Humidity problemsCan 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?

High humidity in the morningI’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 ;)Week 9

Yay, I ordered a growlight + tent + accessories! I'm planning to install all of this in my basement. I have a small window that I could use to send the filtered exhaust air to. but will it suffice to just get intake air from the basement itself? Or would I need an air purifier?
