when are you moving? i wouldn't try and carry marijuana plants out of an apartment building, your just asking for trouble. what are the dimensions of your room/flood table? they (plants) appear to be about a 1 1/2' tall, i would go ahead and flower them and just restart when you get to your new place. your roots are fine coming out of the bottom, just make sure light can't get to them, i would fill the tray with HT, or you can cover it with panda film.
