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

High RH in flower
I find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solution

High humidity during flowering
I don't have an exhaust fan since this is my first growth and I'm quite on a budget my humidity averages around 65-75% I know high humidity increases risk of mould and bud rot is it necessary to get an exhaust fan and aiming for 40-50% or just risking the consequences?

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 ?

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 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

Now getting condesation in my tent when I've added this duct to a pipe exiting the house? Am near harvest too.
Didn't have an issue with condensation inside the tent before, now that I've attached the duct to a pipe going out i'm getting condensation inside... Does the set up look right? I've hooked up to a smaller tent too via a T. Could it be pressure?
