85 is really the max.... also u shouldnt need a glass cover for a 70w hps... get some better ventilation, your plants need it. even a fan blowing toward the bulb will likely reduce temps. and yes i have also heard that glass blocks beneficial rays from lights to plants. no matter what kind of glass it is, it WILL reduce lumens and possibly other beneficial things.
