How important is "fresh Air" in my grow room? I have an 8x8 grow room that is very well sealed. I have a 1000 watt light. I also have a 38 special 75 can filter with a 6" fan filtering the room. The air in the room is filtered through the can filter...the fan sits on top of the canister and pushes the air through my light and then out of the room. I have an oscillating fan for circulation, but no fresh air coming in. My temps are right around 70 degrees...Humidity 45 to 55%. Will bringing "fresh Air" in benefit my plants or am I ok with out it?
