Humidity problems
Can 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?

Temperature Probe. Where to place it?
I use a Vivosun exhaust and control hub. It comes with the temperature and humidity probe. I am curious, based on experienced growers here, where do I place this probe? On the floor or do I let it hang mid-way in the the plant itself?

How do I drop my RH down when nothing works? Check Diary. Will defoliation be a good idea? Open tent door and leave it open?
My 2x2 is starting to crowd. This is driving the RH to over 70%. Should I defoliate to help with crowding and RH? Or should I just leave it alone? RH in lung room is 48% Exhaust fan, high or low with a dehumidifier, doesn't work. What should I do? Defoliate? Thanks! Check diary.

Fan vs Fanless LEDs
How effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soon

RH 90% during Flowering!
I have a problem with RH. I am at the 3rd week of Flowering and I'm struggling to keep my RH down. Today it was 90% when I opened the grow box. I have access only to a window. Is it better to suck air inside or blow the exhausted air out? I can't do both

Currently using a 4x8 tent in a garage that is dusty. would getting a extra intake be better for my plants?
Currently using a 200mm inline exhaust with a max cfm of 537,96 and using a intake with a max cfm of 194. currently using the exhaust on medium setting so 466 cfm. would it be better for my plants to get more air from outside with a new but small intake of about 128 cfm ?

Best Humidifier for 3x3x2 grow tent and best way to set up?
I’m about to buy a dehumidifier. Finding one with programable humidity levels makes them too big 4 my tent & the small ones can’t be programmed to turn off when humidity is too low. Can I get a cheap one with no controls and manage humidity with my Humidistat alone? Will it work?

How crucial is an exhaust fan and a carbon filter?
I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

I just have one plant under a small grow tent. But I haven't set up a ventilation system that looks a bit complicated to me to install. Is it possible to function without if I open the grow tent wildly once or twice a day to change the air ? Or will I be in trouble ?

Circulation / Exhaust
Getting ready to install carbon filter; found myself wondering if growers typically leave their filters/exhaust/fans on during dark periods? Up to this point, I've had everything on one power-strip/timer: circulation fan, exhaust fans, and lights. Should I keep anything on 24/7?
