Best LED temperature to grow SPS

[jeff_a]

I have 3 hydras on my 60x27x27 tank that are managed via the AWM on my Apex. I was wondering what is the best setting and length of time to grow SPS. I have had a lot of success using the 20K setting between 50-80% power for about 8 hours daily. I ramp up/down between 10% up to 80% and then back down to 0% At night, the ramp-down between 7pm and 12am my lights are at about 50% blues and 20% white at varying power settings on the LED. Same with morning but the ramp up is about 3 hours.

I'm not sure if this is the correct forum but I posted here because I have been growing SPS for about a year. Some do great, so do just OK.

Thoughts?

Thanks in advance!
