With this type of combo what bulbs would you suggest choosing and would it be most effective to:

1) Use all blue spectrum T5s for vegging with or without the HPS?

2) Use all blue for veg and then flower with 2 blues and 2 reds and HPS?

I'm just wondering as I have been considering this combo light as well as a 6 or 8 bulb T5. I am still a bit unsure of proper/optimum spectrum percentages during veg vs flower. Since this combo light can provide both spectrums, what would you do?
