Maybe I don't understand your question, but SuperThrive, to the best of my
experience and knowledge, doesn't "protect" anything. It is a synthetic
hormone, B1 concoction designed to stimulate root growth.

I don't know about dens, but overdoing the exposure to rooting hormones has
been shown to result in deformed flowers in some genera.

Ok, does superthrive work well to protect a spiked plant when I changed
medium (yeah I know I shouldn't change medium until the plant is
showing new root groth)

and should I cut the spike on my rootless dend?

BTW does anyone have any experience using Grodan cubes (absnt rockwool)
to help with the moisterure / wicking problem of hydropearls?
