Soak them before you leave and decrease the light intensity. All you have to do is maintain photoperiod.
Either switch to a smaller light, even a few CFLs on a timer, or raise your lights as high as they will go.

You still need ventilation because the heat will cause excessive transpiration and eventual wilt as well.

You can also mist them lightly with wilt-pruf if they are not flowering... LIGHTLY... with wilt-pruf, less is more!!
