I have 2 fans running inside my 3x6 tent. I did have a small fan heater outside blowing in warmer fresh air as it was winter here. Now that it’s spring the temperature and humidity is perfect with just the lights,fans and humidifier. I have 1 300w and 1 600w led. My question is am I adversely affecting my yields by not having a fresh source of air constantly coming in and just relying on 2 open flaps on the tent on either side the fans to circulate the air in there?, they have only been without fresh air blowing in for the last 2 days and just relying the the open flap and fans
When I had the heater going I didn’t have reverse pressure, the sides of the tent seem to bulge out.
I think I’ll just get a decent ventilation system.
