Legalize_it Should i run my extrator from the start? Its pretty cold where i live but with my dehumidifier runing almost 24/day and my lights in a 18-6 cycle the temps in my grow are about 22ºC lights on and 18ºC lights off. When i tried to run the extrator (107 m3/h) my temps decrease a lot, and my tent was like vacuum sucking air out faster than was getting it, i think that can damage my plants. really need some advice on that.
