T5 actinics with LED

[mark]

Currently running 14k MH with T5 daylight/actinic bulbs to allow for dusk/dawn and also to get a little more fluorescence than I can get from the MH alone.

Seems with most LED can ramp up the intensity so good there for dusk/dawn but wondering how many are supplementing their LEDs with T5s?

Guess sort of also wondering the 415nm/400uv with the AI Hydras and Radion Pro worthwhile?
