Forthcoming light problem?

Ok got a plant on the grow at the moment but will have to go home at christmas and am afraid that the landlord will find it. Would it be possible to leave the plant hidden without light for a week and not cause it too much adverse stress? Or else I was maybe thinking that i could set it up in the attic with some sort of battery operation, so as to avoid wires that would be noticed?
Any help would be much appreciated.

i think you could put it in the dark for a week and then put it back in veg.

if anyone else knows otherwise speak up. but im pretty sure you'll be fine leaving it in the dark hidden.
