How to switch to ramping lights?

[b4tn]

My current LED light set up is blues come on full intensity (65%) at 10am and go off at 8pm Whites come on full intensity (45%) at 11am and go off at 7pm. I am changing over to ramping lights and was wondering how can I best set it up without shocking SPS with to much or to little light? I assume I should keep max intensity around the same times but am worried that the ramping period will add more light than they are used to. Here is what I am thinking initially

Blues
Ramp up 8-10, full 10-8pm, ramp down 8-10pm

Whites
Ramp up 9-11, full 11-7pm, ramp down 7-9pm

Any input?
