ok 420,cherokee again ,weather dual arc or single arc for flowering, your plants will take the spectrum they need and disregard the rest during flower so the extre blue could only help with stretch problems hps is known for it cant hurt and can only help during flower, the blue is a benefit more than not if you dont want alot of stretching? hope i understood ya correct?
