I run one that blows over the top of the soil and another over the canopy. Don't see an issue with what you're doing

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?

So has anybody used these cordless mini dehumidifiers in their grow rooms? They’re small units that u charge over night every so often when the silica changes colour? My grow room is very small so an electric dehumidifier wouldn’t fit and I’m struggling to keep humidity down

In-line fan use
I’m just wondering how much to run an in-line fan. I’ve read every 1-3 mins, but I would like to know how long does it run in between those times? Is it constantly turning on and off? Do I need to put it on a timer? Thanks.

Cardboard box method for dehumidifier
Hi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?

Just a quick one people, I only have a outlet fan in my tent? My tent is 70x70x160cm if I open the bottom vents on my tent would this be enough air for the flowers at later stages if I open a window in the same room to allow fresh air?
