T5 Veg spectrum

[khyberkitsune]

You've prolly already made your purchase on lights. t5HO 54w actinic 420nm-460nm lights are what you want for maximum veg growth, coupled with a t5HO 54w Roseate 650nm flower bulb for maximum bloom.

The actinic phosphor is too inefficient in output - the 420-460nm phosphor used in computer CRT monitors is far more efficient provides superior photon flux density per watt of input power
