I'm sorry I can't answer your question. I only have one NOID that I grow, and I believe that the leaves on that have already broken ground. I believe your plants will probably be fine as long as it doesn't get too wet. But OTOH, I'm in a warmer zone. But I have a question for you: is that A. Shuberti in your last two photos? I love the entire plant. It is a show and heart stopper
