hey justin, i am assuming these plants have been on a 12/12? and now u must leave for 5 weeks and in order to care for them u must put outside and let mother nature care for them?
if this is the case, what will happen depends on how mature the buds are now, if they are "mod way" your harvest will not stop, but it will slow considerably....
can u just go buy an automatic watering system and light timers? i would reccomend that method or maybe a friend can care for your girls while your away....
