C. dowiana - clues on mature growth

[piping plover]

Hi all. I know that this species needs a dry warm season after growth matures and I don’t want to get the culture wrong by watering when I should not be. Does this growth look mature and ready for the rest season? Should I wait until the papery sheath dries up? Trying to verify the clues to look for.

I don’t think it will bloom this season with no bud sheath. It did grow 3 or 4x larger than the previous growth so I think my indoor lights were really effective thus far.
