December 9th:
Found out why the plants look like they started revegging...
It's because they started revegging. The timer burned out and kept everything on 24/7. I'm glad a fire didn't start, but it sure was close. I think I caught it just in time, or there would've been a fire.
So, who knows when these will be done now.
@Ju_Bps, thanks, friend.
I'm bummed the timer melted and I didn't notice until the leaves changed. I got comfortable and lazy with this set-up, so I've been making sure to check on everything at least once a day. I learned a terrible lesson and I don't want to repeat it!
