4'x8' tent with two 400 watt hps

Would two 400 watt hps lamps do good in a 4 foot by 8 foot mylar tent? I just started some white label super skunk and am now trying to get my flowering room togather and those are the lights i already got from last year.....

For sure! Just make sure you have a good exhaust fan and air cooled reflectors if possible. Good luck with your grow!
