I get what you are saying, do you get that I'm saying a true purple light can't be split to red and blue? Throw pure purple through a prism and it doesn't split. The light you are talking about appears purple, it's not purple

I did, but in your fist post you talked about it you mention one light that was duel and then a purple light. Till you posted that I had no idea what kind of light it is.

Yes, I agree with that, and yes, the light that 'purple' cfl's emit isn't true purple, in fact, some company's advertise them as red/blue cfl's, but they do look purple, and most people call them that. You can mix light and get different colours, red and yellow light will give you orange light, yellow and blue will give you green.
Edit - Actually, I think that if you were to spilt a purple light with a prism that was made of red and blue spectrums, you would get red and blue, but I cba to find something to prove that.

Also I've tried experiments with aquarium lights where the spectrum was very narrow and found that I actually had better growth with a whiter mix then just sticking to the peaks, which honestly I didn't expect.

I read a report somewhere that said that replite aquarium lights (some varietys) contain too much UVB, which is harmful to plants in too large doses, but good for them in small amounts.

That could be the reason, I have no idea. But the lights are supposed to be used for growing the plants in the aquarium, maybe the water filters out UVB?

Most threads are actually answered within the first few posts, if so then they are reborn into whatever mess the participants want to take them. - Japanfreak Pot Board Rules paragraph 3 section B.

i said i was 2 weeks into flower i meant 2 days. so will i be safe if i keep the 6500k bulbs for just a week, i need to wait till i get paid. and the 2700k bulbs are more towards the red spectrum right??? or blue??

You should be going for mostly red. Althought there is a good arguement for doing the last 2 weeks of veg under mostly red also, to help the plants adapt to the new lights.

red. if you look at your lights now they have a blue/white tint when on correct? When you switch to 2700k they will have a red/white tint when on. You will be fine for a week but to those lights in asap after you get paid. the red spectrum replicates the summertime light that plants would get outdoors when they would be naturally flowering. I dont know if the shorter days (12/12) and wrong light spectrum (6500K) will confuse/mess up the plants, but its not going to help you get that dream harvest either.
good luck

I would still go 50/50 on spectrum. if you had 3 i'd say 1/3 and 2/3 like everyone else has. What size are your bulbs and your area and how big is your area? your not gonna get very much unless you improve your lighting some. Think of it as an investment, for 30 bucks you can drastically improve it. Heres what i started w/before going to hps, although i used 42w not 26w but the 26w will be much cheaper for you. Alright, go buy 2 lightbars, 8 outlet to socket converters, 8 y splitters, and 8 26w 2700k and 8 6500k 26w cfls. Take your outlet to sockets and plug them into the lightbar, 4 each bar, now screw in your y-splitters to the coverters, now put 1 bulb of each color in each, alternating them so the spectrum is mixed up and you dont have 2 of the same color next to each other in the rows.

Can you show the links where to get the spliiters & socket converters . how much they cost?

I don't do lumens but a good rule of thumb is 50 watts per square feet or higher to flower.

that makes absolutely no sense. you should "not do" watts if anything considering its probably the most useless measurement.
lumens is something that can be accurately measured or compared to other light sources.
I'm sorry for misguided information^, but for two plants you should be aiming for around 10,000 lumens ideally.
