Is high humidity at night bad for cannabis?
During day, I can maintain the grow room temperature to 75-77'F and humidity 55-65%. But at night, temperature raised up to 77-80'F and humidity up to 70-80% because I closed vents and air condition. Could this effect my plants in long term? Should I open vents at night also?

Smell through filter exhaust
The smell inside is quite strong and is coming through the filtered exhaust. Is this normal, or does it mean I need to replace my filter soon?

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?

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
