to many things can go wrong. Bugs, moisture, heat...All these things in attention pretty quick. Survival is the term you looking for. Your most likely screwed for a decent bud return on this grow imo. Good luck though. I say some kind of drip system using a 2 or 3 liter bottle. They would most likely be overwatered early and underwatered later in wk 2/3. Maybe even out but costing bud return....No friends to help? Try it but be lucky if you don't find a big problem when you return? You haven't mentioned what part of flowering so that might help?
