Upgrading my fixture from 150w hqi to 250w hqi.

Looking at 10-14k for growth. Growth is my main concern for SPS and LPS.

bulbs for consideration are
XM
Pheonix
Aqualine
Hamilton

I've heard great things about Pheonix. Some say greta growth and color. good price.

I've heard seriously mixed baggage about XM, some say that the color is good but doesn't stimulate growth. Want to hear more as XM has great hype.

Hamilton seems to be an old standby, industry workhorse.

Comments suggestions. I want to hear them all.
