ya dude im 16 living with my parents...so i don't think i can keep it open like that, especially with me working so much. but ya i'm gona try and get a some more fans. i do open up like 4 times in 24-hour period ususally to look, and for like 15 minutes each time. does that help ventilation wise?
but ya i'm guessing from your answer that 28 degrees is pushing it?
