FYI,, i am almost positive that 3000k is more in the orange spectrum... red is conductive to stem growth,, and this is the spectrum that incandescent give offlike he said, the red light is recommended, but if you dont have an option, then i guess your using 6500k, just not the best for flowering, as blue is best for veg growth
and no, you wont be able to tell the difference,, the yield may be slightly lower than if you would have used the proper colour temp but not enough for you to really spot a differenceso using 6500k for flowering wont effect the bud that much? I know i worded the question messed up on my first post i wasnt right headed
rep up bro
