If it is week 1 of veg then a small fan on low power, just enough to move the leaves a little bit. Later on - both bad boys on. Big fan on the top, small one on the bottom. Good luck!

Are (constantly) high daytime temperatures a huge problem in flower?
My day temperature since turing my light up to max during flower are reaching 29-30c | 84.2 - 86f, while the daytime RH is at roughly 40% - 50%. Is the high temperature something to be concerned about? pics 1 and 2 are the exact same data as pics 3 and 4, just set to c/f each.

Do I really need a exhaust fan ?
If my 2x2 grow tent sits at 26c and 68% humidity without an exhaust fan do I actually need one ? The top of my tent, the vent is open and I’ve opened the observation window at bottom to allow air in. I’ve two fans, one at canopy level and one in top corner opposite the top vent ?

Heat
I’m thinking of putting a 12” fan up high to move the air to one space and an extractor to take out the air and a second cooler as I got up to 30c on a day of 15c so need some measures! Question is will it work? Don’t want to waste time on pointless things!

I am facing a temperature problem again....
My tent reaches 84.2F, which is too hot in my opinion. But my humidity is perfect. On the other hand, if I activate the ventilation, the temperature of the tent reaches 76F, which is perfect, but the humidity level drops dramatically to 35%. 1- Keep Humidity or 2-Keep Temp

grow tent / lung room temps???
Dialling in my tent and want to compare to others to see if more ventilation = lower temps. What temperature and humidity difference do you have in your tent and "lung room"? Do you exhaust your air from the tent to the outside of your lung room?

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)

Carbon filter sleeve needed?
I use the carbon filter on the exhaust side. On the intake side, I have a dust screen mesh. The tent is quite clean so that’s why I don’t see the need of the pre filter. Would also probably load the inline fan a bit too. What’s you thought?

Growtent Humidity control
How do you control humidity/temp when using a grow tent? is it enough to put a dehumidifier in the same room as the tent and close the tent and just blow the air outside with a fan and tubing? Do u need an intake fan too? Or does the "good air" gets sucked in enough without ? THX
