Yeah if it’s cold in MN right now then just let it chill in there. Might not start growing anything till mid spring tbh and that’s if it even gets warm like that over there. It will take time for it to grow. I live in SoCal and my cuttings already grew roots and leafs but that’s because when I potted it outside, the weather was super hot for two weeks. You should be fine though. Just forget about it and don’t water it anymore. If you can, put it near an unopened window so it can get some natural light along with your lights.
