it's getting too hot. I added 2 fans inside. Do you think I can enable them 100% of the time/all day? Or is it bad for my plants?

Set Up Tent
How should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?

Carbon Filter smaller than Fan
Is it bad if the Fan makes 200m3 but the Carbon Filter is only for 100m3? Do I need to change it as quickly as possible? (Tent 60x60x160)

Co2 bottle question (Tnb)
Should I be running my exhaust fan and intake fan during the day while I have a Co2 bottle in the tent, or will Scrubbing air make adding it useless?

Messy Extractor Install
Bit of a mess this! Though I do have a smell-free grow area now 😇 Would there be any issues with putting the fan outside the tent with the filter inside at the top and ducting going out and down to the fan? Thanks

What u guys think im good with all smells with Vents TT125 220-280m3/h and Phresh filter 500m3/h? I think 500m3/h is little bit oversized but cant find smaller Phresh filter with 125mm flange but what i read oversized filter isnt bad thing?

Can I exhaust my grow tent into the closet it's in?
I'm putting a 3x3 grow tent into a larger closet I have (maybe 8' x 4')? So I guess the closet is called the lung room? I will have a carbon filter and inline fan in the grow tent exhausting out. Can I exhaust out into the closet it's in? Or is that a no-no? Pros and Cons?

I'm after a new duct fan. Needs to push at least 400m3 per hour. And the main criteria is noise. Below 21dba would be the dream.. curious to what folks use and if I see one that meets my criteria I will buy it.

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?

I can't control temperature. I'm so discouraged.
How are you guys keeping temperatures down!? I have an hlg 600 Rspec at 50% power and the Temps won't go below 81 degrees with the light on. I'm in a 71 degree house. 4x5 tent with a 400+ cfm fan and negative pressure. I also have fans blowing on the plants and the light.

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!
