I agree w/Lool, take it off. If I have the cubes on my workbench with seeds or cuttings I leave them on, when I move them into the mesh pots of the hempy buckets I remove the plastic at that time.
I leave them on just because, when I don't, the roots start to grow into the rockwool cube next to it. Then when its time to move them to the bigger pots, some of the roots tear off. Can't be good for the seedlings.
