I think bluer bulbs are all the rave right now
Coral growth with 20k's is said to be slower though. I have been looking at 14k's myself. I worried that 20k's would be too blue. I had a LFS
tell me I could try 20k's and use 10K suppliments if needed.
It would be good to see one in person if possible.
You could always get a MH
retro kit and just build a simple wood surround and hang it. I know a guy that did this with his 125. This might be cheaper.
