I have a hurricane 6inch inline fan pushing in 435 cfm into my tent and just a booster inline 8inch pulling out at the top. Im running an led so the light is not the issue. The issue is i have my hurricane secured to pull from the air directly outside. On days its 90 and 100 plus degrees how do i keep my tent kool with that hot air getting pulled into my tent w.o completely cutting off introducing fresh air from outside an only pulling air out?
