Does anyone leave their tent partially open when lights are on? I have a 4 inch and 6 inch exhaust. If I run the 4 inch and keep my tent closed, it can’t keep up with the high temperature from my light. If I use the 6 inch, then the humidity drops down to like 30% and my humidifier can’t keep up. Any advice would be greatly appreciated. ---

How? I already have two oscillating fans in there. ---

I bought piece of duct work that slid right inside mine and ran flex duct for AC… ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/b/b/c/bbc584c5cfe9bf74dfc5ac5cd4e53607771cc5af.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/0/5/5/0556e285ce1109acf87045e35717ce55468c73b1.jpeg) If you can it works great… Happy growing… ---

> [@rvf239](#): > > two oscillating fans Fans only increase air circulation. You need to increase air throughput through the tent to manage temp or RH. More air in and more air out. ---

Your tent has vents on it open them up… Raise your humidity level will also get your temps down… ---

How do I increase airflow then? ---

I’m on day 19 of flower and my humidity stays between 49-55%. ---

Increase airflow via both input (bottom vents) and output (top vents.) ---

Maybe I’m an idiot but I’m not understanding. So keep my 4 inch exhaust at the top vent and use the 6 inch at the bottom vent? ---

What size tent are you using? One 6 inch exhaust fan will turn over more air than needed in a 4x4 tent with no problem. ---

I’m in a 5x5. This is my first grow in it. I feel like the environment was much easier to control in my 4x4. I don’t know how to stop my 6 inch exhaust from sucking out all the humidity. I mean it drop from 55% to 30% in just a minute or two. Makes no sense. ---

Then if I use the 4 inch and keep my tent closed the temp goes in the mid 80s. It’s a lose, lose. ---

Hopefully you have your exhaust fan on a variable speed. I control the temperature and humidity in the lung room that I pull my fresh air out of 12x10 room with a 4x4 tent inside of the room . ---

I was assuming you were in my situation … My tent was running hot cause temps outside here are rising… AC works perfectly for me right now 3rd week since I have flipped to flower… My temps while lights on are right around 80 And like 68-70 lights out… Happy growing… ---

I have the 4 inch on medium power but even on full power it’s not strong enough to keep the temperature in check with the tent closed. My lung room stays between 65-70. When I tried the 6 inch on low that’s what sucked out all my humidity. [Next page](https://ilgmforum.com/t/grow-tent-open-or-totally-sealed/117970.md?page=2)
