12/12 = 2700k?

When I switch to 12/12 should I also change the lights to 2700k vs. leaving in the 6500K ... yes a noob question

I'd wait two or three weeks into flowering before screwing in 2700k bulb to minimize initial stretch.

I go from 70% 6500k to 70% 2700k at 12/12. Just one opinion.

I always switch lights when I change cycles. I do 24 hours dark after veg, then switch to my HPS light for 12/12. The quick change in spectrum helps the plants recognize that it is time to start flowering. At least that is what I've read. Some people claim that plants show sex faster this way. It works for me, but I've never tried leaving my veg lights on a few weeks into flower. Might have to do some experimenting to see what works better.

yes wen u flower u have to change the lights to 2700 and u can start with 20/6 then switch to 18/6 lil by lil to get the plant think winter's comin then u can switch to 12/12 i did that with my first grow good luck
