Actinics?

[fkshiu]

Actinics give you more flexibility. You can run dawn/dusk cycles, but more importantly, you can run a lower kelvin MH bulb to get the benefit of its higher PAR value by offsetting the overly yellow colour you get with actinics. I disagree that MH will drown out actinics. I run XM 10K MH bulbs which are quite yellow. When I turn on my T5 Actinic+ and the VHO UVL Superactinics, the colour is balanced out to a nice clear white.
