Never tried and never will as it is sure odds on to fuck them up.
Bro it's your moms Bday. Grab a light timer and use that? Give them a huge drink. Why can't you leave the lights on? unless they are in flower? It looks like you haven't flowered yet. Just leave the lights on.
I will definitely do a sog if u have to go just to be in the safe side..
Drippers would work in veg, even those Blu-Mat's for a week. Problem with drippers in flowering or for any longer than a week would be having a large enough reservoir to give them water. Leaving them in the dark for 2 weeks though, not sure what they'd do. I've left them in the dark for 6 days and they didn't look like they even knew anything was wrong. More recently I just shut down my flowering room (did a large run and timed it to finish before I went away) and kept only veggers going, freshly transplanted into 3gal from 1gal pots, then had my son water them once, turned veg lights down to 16/8 to reduce water uptake/evaporation further. I'll likely do that again if heading out for a week or longer, it's relatively easy to keep veggers going if you up-pot into large containers just before leaving, then drippers or someone trustworthy popping in once or twice.
You need a better grow with more automation really, this will come in time but anything else is not going to be productive.
