Red and blue colored grow lights?

what kind of light are you talking about?LED or fluorescent? with LEDs many people add deep red to white LEDs for a better spectrum. with florescent cool white is used for vegging and then warm white is added to shift the spectrum during flowering.horticultural panels from companies like CREE use 5000k white leds with photo red (660nm) LEDs added to improve flowering.

I thought so too, but he mentions "white light", which I'm guessing he's referring to HID, not cobs.
OP, if you're talking about the colored "grow bulbs" on ebay, just, no.

Cree doesn't make panels.

Link?
"White" light is typically going to be a broad spectrum light which will include both reds and blues at varying intensities. So yes, you can mix "white" light into your fixtures without any issues.
I would think it's best to use your broad spectrum "white" light as your primary lighting source and only amend with narrow spectrum blue or red LEDs if you feel the need for it.

very similar to what NASA is currently using. cree uses 4000k white while NASA uses 5000k white. both lack UV and 400-435nm light

i was thinking about building a 25% model of this and seeing if it works. But full cost worked out to be around 800 usd so 200 for my scaled down version. Too much for me to test. During my searching the opulent north america modules caught my eye so i may go that way. Heat sink, module with cree xhp leds, and lens for around 100 usd per 100w. Everything is predrilled and the heatsinks lock together for adding on... .drivers not included.

My bad for not being more specific, I'm talking about an e27 LED light... it's not just spectrum color, it's the kind that is blue and red visible to the human eye.. I just bought it online and when I plugged it in, it just seemed like the regular white lights I have on just cancel the red/blue colored lights out..
I was basically asking if it's ok to mix these different types of light...
I kno this is more than likely a dumb question but I just wanna make sure. This is my second Grow ever and it's my first Auto(white widow) so I wanna get it right ya kno?
Thx guys

Its fine to mix them. It won't cancel out.

is this the kind of bulb your talking about ? http://www.ebay.com/itm/LED-Plant-Lamp-Hydroponic-Grow-E27-12W-Light-Bulb-For-Garden-Greenhouse-OE/112216772370?_trksid=p2047675.c100005.m1851&_trkparms=aid=222007&algo=SIC.MBE&ao=2&asc=41375&meid=188c909af9fd4e6bb0ec0d683b59cd3c&pid=100005&rk=6&rkt=6&sd=272354686419 mixing these with white LED bulbs should work fine

Those look like they have potential too, and good efficiency.
The opulent modules i was looking at are here http://www.mouser.com/ds/2/810/XHP70-Modules_DataSheet-974838.pdf
i really like the fact that the heat sinks lock together for adding future modules or removing them if need be http://www.mouser.com/new/opulent-na/opulent-cree-xhp-heat-sink/

Those things are a waste of money. I mentioned that at the beginning of the thread.

Wasting money and will they work are two different things. They would help fill in the spectrum missing from the straight white led bulbs.
