Thanks to everyone who responded but I should've actually looked at the bulbs before writing the post. So I cannot run the Radiums as I have double end bulb fixture. Also as far as the ballasts go, I will post a pic below. I know its probably not as nice or ideal compared to what a lot of you guys are using but they work and came with the fixture. I have been really happy with growth over the prior year since I put up the fixture. I am not interested in changing the ballasts or the fixture at this time as it is a combination MH and HO t5.
So the real question would be what are your opinions on the best double end bulb and if anyone has some FS/FT please let me know. I have heard great things about 14K phoenix but have not seen them in person. I prefer a little more blue and flourescence so I was also considering some of the Giesemann Megachrome 17.5K or 21K. I supplement the MH with 4x HO t5 and 2x Kessil A350's. Insane growth is not my primary concern even though I think all the supplemental light helps a lot, it is more of a balanced growth and pleasing look leaning more towards the blue side from the MH that Im looking for.
