no growth tip.. so it won't do anything for a long, long time... if you care to wait for a new tip to sprout out of it.
assuming it lives, it iwll happen at some point. i've seen a new growth tip sprout from a harvested autoflower - Just a stump with no leaves. if it is an auto, i'd just toss it. even if it's a photo i wouldn't bother unless it's supposed to be something special.
