oops, missed the deadline...
I have had to leave plants alone under many circumstances. Next month I have to hide my grow (no lights, no water) for five days. Not a worry as they will be in bloom cycle. I'll leave them in the dark and not too moist for only five days. I've done eight days without a trip up.

For my seedlings I'd reduce the lighting but for skrengf's grow style I'd not do that.
