Nice one fuerte!
I took these pics an hour or so ago, just for re-assurance. It will all be good and ok.
The first pic is of a straggler flower (the flower facing the camera) that opened just yesterday - while all the other flowers on that spike had been opened for quite a while now. And the spike is producing more buds - coming out the ends of the main spike, and also producing a secondary spike.
The other phal is doing something similar too ----- producing spike extension from the existing spike toward the end of its long round of flowering.
This is only for assurance that the phals can grow in scoria no problem at all.
The last pic just shows where I water (using my spray wand). I just water the outskirts ..... spraying lots of water into the pot outskirts.
I also spray a little bit of water (but not that much) toward the centre (if the leaves aren't blocking) ..... just so that some roots toward the centre can pick up or gather any nutrients that might be hanging around in the scoria. The central regions of the pot definitely don't need to be dry or completely dry.
The two phals are doing nicely in the tropical conditions here.
