Lighting and Heat Questions

I am using a 400mh in a 4x4 grow tent now.I have 9 plants in 3 gallon pots going,using fim and LST methods.I want to get more light so my buddy gave me another 400 watt HPS.Temps run about 77 but as soon as I started the other light they went up to 85 before i shut it off,I really want to flower with 2 400 hps.Question has anyone else ever done this and what are max high temps,any other suggestion would help

I also have two fans going

use cooltubes if you need to cool your lights down or vented hoods.The max temp should be around 25 degress duno what it is in FH(think like 80 max) .Or run your lights at night when the ambient air temp is lower.Or get bigger fans

can u connect an exhaust fan with ducting off your hps bulb.

no both are not equipped to do that
