I read it's important to exchange the air in your grow area once per five minutes. Because I read that, I've had my inline exhaust fan running in my tent since the beginning of my grow. Is that right?
Most run 24/7. I personally run mine 15 on 15 off on timer due to keeping temps warmer in grow area. But regularly moving air is needed to exchange new air and control humidity. Good luck and happy growing 🌲🌲🌲👊
