Grow Tent Ventilation.

hello all. I have a question that I can't seem to find a reasonable solution to. I purchased a grow tent, being 36'' long, 20'' wide, and 64'' tall. inside of my grow tent is a 400 watt MH bulb, 5 plants, desk fan, and a humidifier. my question is, I have two 4'' inline duct fans, rated at 80 CFM. I was wondering if I should exhaust using the two? currently it's setup to bring air in the bottom, and exhaust it at the top. I've seen many people objecting to this setup. should I use the two both as an exhaust being that my tent has ventilation flaps located at the bottom? please point me in the right direction towards the best setup. my tent stays at a stable 79 to 85 degrees.

stays relevant.
Negative pressure is good. Try other variations and stick to what is best for your particular situation. :)
