New to LED growing but I already have my fixture in place. Just a common question though but what spectrum am I supposed to run during veg? I'm running 3 autos atm so no need to switch light cycle so...should I just run the red+blue spectrum all the time or should I just run blue and switch to red when I see them starting to flower?
Does it matter for photoperiod strains? The spectrum of light if the cycle is 18/6 for example.
