Monti cap placement

[Back where it all began]

Hi,
I did some research but didn’t get a good answer. Can a red monti cap be placed at an angle to the surface/lights, or does it need to be essentially flat so all of the light hits the surface evenly? I’ve got one that’s several weeks in the tank and it’s got a bit of fading . I know that can be normal as it adapts to new water parameters, but I’m looking further ahead.

I have one(my first) that I placed flat so all of the light hits the surface evenly and what is it doing? Why growing up the side of a rock at a 45% angle. Since that one I've glued them down at many different angles and they grow just fine.

I appreciate your thoughts. Seemed like it should make no difference, but nice to have it confirmed.
