Once my grow season is over I'm going to move a few select plants back inside to continue fruiting over the winter. In the past my small closet was perfect because I only had to exhaust the air a few feet. However in my new location I don't have that option. I could cut a small circle in the closet ceiling and exhaust directly into the attic, but I'm not sure if that's the best option. I can also exhaust the hot air about 10' away to an open window, but not sure if that distance is too far or not. Any suggestions? I will probably run a single 1000 watt HPS in a cool tube for the 3-4 plants.
