Tropical Black Culm Close-up

G. atroviolacea culm in the process of turning black. You can see the daily growth marks left where the culm sheath was. It doesn't look like much growth, but this takes place between all nodes, so if you have 20 internodes, then 20 times the above distance begins to add up.

My pet ladybug for size comparison.

Stretchmarks... Looks like it's growing in quantum leaps, bursts of growth. I wonder if you saw time-lapse photos if it grows continuously or in bursts.

A couple years ago I recorded time-lapse of tomato seeds germinating.

I think it grows faster during the nighttime hours, than it does during the day. During the day, my thoughts are that it slows as it gathers more sunlight and then produces and replaces the stored food.

I measured Henon growth a few years back, and when I measured it at six hour intervals, it grew faster at night vs the day. 14 inches in one 24 hour period was the quickest growth that I recorded.
