Hey all. I'm more than halfway through my first grow and are currently dealing with a bit of a problem. My grow tent is in an unheated concrete block room (Room temp is very stable) but within the tent, I'm having a hard time keeping the temps below 80f, the humidity below 70%. As such, I've taken to opening a couple of the air intakes and leaving the door 90% zipped. This, I believe, is contributing to the increasingly noticeable, odor while hopefully, keeping the temp/humidity somewhat lower! If I zip it up and close all the intakes, the temp/humidity will only get worse.
As the 3 girls have gotten bigger, the humidity seems to go up more than before, so I do need to play with setting on the humidifier but I think I'd still have temp issues.
Are there options to lower the temp/smell? I likely WILL be getting a larger tent next grow...should I just get a bigger/more CFM charcoal filter? Any suggestions are greatly appreciated!

You mention you run a humidifier, what type of water do you put in it? Just wondering if you are putting tap water in there then you may see mineral buildup on the carbon filter sock which will restrict air flow. If that's not an issue, a 6" ventilation setup would help exhaust more of that hot air out of the environment. What is the RH in your lung room?
Thanks for the info...have a few things to try! I'll attach a couple pics that show my setup. I am in the So Cal desert so our RH is usually quite low!
Plants transpiration adds to the humidity, the bigger they are the more water they need the more they transpire, the more humid it is. I suggest a dehumidifier with RH% sensor, otherwise you will need a monitor that will automatically turn your dehumidifier on.
For the heat, if the location is secure of insects like spiders, I would suggest keeping the any observation window open that is at the top end and above the light (so long it is screened). This will allow the rising heat to leave. If you have an opening on the top that can be screened by you, get creative, it can help with the heat leaving as well. These two can help to lessen the running of your exhaust.
I am in a basement that is not climate controlled at all so I understand. The cold is my problem. I've had to automate the climate almost entirely.
You will have to get a handle on that RH if you don't want bud rot and mold issues during flower. Also, be careful leaving the door open. If you have too many light leaks you may herm out overly sensitive plants or cause unwanted stress . .
Are you able to post a picture of your current setup? Just want to get an idea how everything is connected and laid out.
