LED lights

    I own some older LED lights. They have separate switches. One for veg, the other for flowering. I've noticed that most newer LED lights don't have switches. All LED's are on all the time. I've done several grows with my current lights with no issues. I'm currently in about my 4th week of flowering with only the flowering switch on. My question is would it help, hurt, or make no difference if I turned the veg switch on too? The flowering has mostly red LED's with a few blue. The veg has a combination of red, yellow and blue. I can turn both switches on at the same time if I want to. I just don't want to hurt the grow if turning on both switches would hurt them.

    I always ran full spectrum with my old blurple lights.

    I third it . Both on. You can run any spectrum in flower . But with your purple the plants will benefit from the mixed spectrum to give you higher quality and a bigger yield .
    To answer your question the new lights have a mixd spectrum. So using both switches on is a mixed spectrum.

    Both on. More light. Just be careful its not to much light, you might have to raise the light a bit.

    Thanks everyone!! You all said the same thing. Turn both on. That's what I'll do. Thanks again.

    Yep, just watch your temps. Thats probably going to double the light/heat.

    The lights with veg and bloom spectrum usually have more blue in the veg and more red in the flower. You can run veg during veg when less red is needed or desired, sometimes causing tighter node spacing and also saving watts and reducing accidental light stress. Then at flower add the flower spectrum (run both together) for a more complete spectrum and more watts and more par.
