Weezy90answered grow question 6y ago Hi!
Follow along with the other plant, the autoflower you already have. If the random seed is an autoflower, it will start to bloom on its own, sometimes even from week 4 (if you have a fast bloomer 😉) Then you'll know. Definitely don't switch to 12/12, just wait and see. You will disturb your other plant. So hoping for an autoflower, I would say: crossed_fingers:
Good luck with growing! 🌱
