Have a 5 x 10 grow tent in my basement. Planning to run 2 x 600w for veg and 2 x 1000w for flower. Have a 6'' inline fan and filter, trying to figure out ventilation. I am in the north. Will be 55 and below starting mid october. I was thinking ducting to a vent to an above bedroom, blowing hot air out up there, could be an efficient way to heat the room. But I dont know how loud that expelled air will be and if any danger comes from venting into a living space? I could also install a vent to vent to the outside, trying to figure that out or what way would be best, above bedroom would be really easy. I would then have intake be passive, pulling air from basement. I was thinking run the lights at night when its cold, and in the day run a heater when needed to keep at 65. Any thoughts or opinions? Thanks yall.
