need a humidifier or ignore it. with a furnace on you are likely around ~30% RH.
could reduce temps a tad, but if near ~20C, that's not a good option for you. temp and humidty are related as far as what the plant will enjoy.

Best way to cool 5x5 tentTrying to find a way to cool a 5x5 tent, the ambient temp in the room is a sweltering 100 degrees. Is there some kind of AC unit that hooks directly into an inline duct that I can pump directly into the tent? Looking for an overall solution to temperature control!Setup. Ventilation

Ventilation questionIs it possible for me to take down the walls of my tent and leave the frame with the lights on it to let the plants get more space? I don’t have a way to ventilate the entire closet from an external source, just been ventilating the tent w/ an exhaust fan and carbon filterWeek 5

Smell problemI have a small tent from airontek, not the best in quality with a carbon filter and extractor inside the box, but the smell outside is too strong. When using carbon filter do i have to expect to have (almost) no smell or maybe Im doing some mistakes? The smell is very strongSetup. Ventilation

couple quick questionsDo 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?
