hey there Legalize it, yes, you should always run the extractor so that the air circulates, if you dont you're basically asking for all sorts of mold, in the soil, on the plant, on the grow room itself... always run the extractor. anyway you'll have to run it, so might as well start figuring it out now. What you can do to raise the temperature is get a small and cheap space heater, put it in there, turn it on, simple as that man. Hope this helps ! 🚀
