I would say Chalice is on the slower side growth wise.
In my very limited experience, I had a piece that did literally nothing for over a year. I moved it to a spot so it was on a 45 deg angle and it started growing.
So is this to say it's because of the angle? Lighting and flow are certainly different in this new spot too....
I've been told medium flow, medium light, and put on an angle. Worked for me , YMMV
