Blue Light in Flowering stage?

[UtopiaGrower]

Hello everyone here, i'm in flowering stage with my little garden and
i have 2 a 400 w hps agro , 2 tled blooming (red light led) and 1 tled growing (blue light led).
My question is : Should i let my plants only under red lights during flowering stage
or can I turn on the 1 tled growing with the blue light ?
I attached a couple of pic

Personally, I would flame them all as long as you don't fry the plants. Natural sunlight also contains the blue spectrum . . .

Before I played with LED's I only used MH and those were 600w bulbs at 7,200K.
Those are very blue daylight like natural daylight. I never liked HPS orange type color.

You can actually go thru the whole flower cycle with nothing but blue spectrum bulbs, it's not considered optimal but the plants will still do fairly well. Mixing blue and red spectrum is fine and as tobedetermined pointed out natural sunlight has some blue spectrum light. it has to do with the angle the sunlight enters the atmosphere. In Spring the sun's position relative to the earth has it coming in at an angle where the sunlight is mostly blue spectrum but there is still some red. As the relationship between the sun's position and the earth's position changes from spring to summer to fall, the angle the sunlight comes in changes and the atmosphere refracts it more as red then blue but like there is some red in spring there is still some blue in the late summer early fall. Plants have adapted to this and that's why veg growth is more suited to blue spectrum and flower is more suited to red spectrum but both spectrums are always there it's just the amount of each changes over time. So adding the one blue light will make things more like natural sunlight. It's probably not going to make a huge difference but it won't hurt it and many growers will say the more like natural sunlight the better.

Utopia you are doing a good job and your grow looks awesome. A proton is a proton in flowering and I like to get as many as I can. Full steam ahead.

Yeah man, more light is better if the temps can be mantained.
