I second that. Unless you have an autoflower your plant will begin its bloom period when you change the lights to 12/12. The light colours you have are also not the worst thing in the world for veging - your plant won´t be suffering. I´m not saying don´t change to 6500K but just don´t panic about having to do it immediately.
All the best
rattlingdags Reviewed by rattlingdags on . Lighting Issue Hello, I have a few questions, I Just built a grow room and Have 4 (4' FL 5200k lights) and 2 (23 watt spiral cfl's running at 2700k). i bought the lights not looking at the color temps. So I have a vegging plant and understand that I need 6500k spectrum, now does the light spectrum effect the plants ability to start flowering, or does the lighting time such as 12/12 play a bigger role. Basically, all I'm asking is that will my plant suffer from a couple of days under these lights until I can Rating: 5
