That’s the big question. I’m just curious if it makes a difference.
Do you have a bloom and veg switch on your light? If so run both the whole time.
6500K or so(more blue light) is optimum for veg. 2700K or so (more red light) is optimum for flowering. N it each is mire effective at what its good at. But as long as the girl gets adequate amounts and intensity of light. She will grow
What light do you have led or mh/hps
The answer to your question is yes.
Once an auto hits flower u treat it just like a photo. Aside from having to have complete dark.
T-5 for this grow
