Indoors Prop Station Update2 w/ Mystery Kalanchoe

The two bio domes on the right are cuttings taken a week apart. To my amazement
is the one at the top that is a week younger but doing the best.No premature dropping
of leaves, no yellowing. The difference between the two besides time is the top one
has rooting hormone.

The only two times I ever used the stuff, resulted in two fails. The only reason I
had some on hand was because a budding plant enthusiast and yogi buddy gave
me some. Like a plant cutting , how could I refuse. Too early for glowing results
but it does look encouraging.

A large leaf Caladium cutting nosing in for some 24/7 light action.

 My first HP floor prop and even looked around for it's donor for identification
purposes. Initial internet search resulted in nil. What's a little challenge?

A Kalanchoe of some sorts.
