You might have a hard job as red and blue are the only required colours and people wont spend money on purple,green,pink ones that don't emit the correct wavelength

its not rules.
its called tried and true! experiment and research.
but you go ahead and try out different colors that have been proved irrelevant to plants!!!!
wasting your time, not ours!!!!
This is part of the artical that sparked my interest
" when it comes to LED grow light systems. When planning such farming alternatives, one has to carefully consider that plants do use light at all wavelengths from UV to IR, as explained above, needed to convert water and carbon dioxide into sugars. Some plants use more red and blue, less green and yellow, while others use green as much as they use red and blue, as well as the light in between"

oh my goodness
ever since the invention of the light bulb, they've been testing wavelengths/colors on plant growth. 400 and 700 nm were always the two peak wavelengths. 400 is blue and 700 is red.
also everything in between is needed to grow but at lower levels. Thats why you need full spectrum bulbs to have a fuller plant. if you only have red and blue your plant will be a runt.
dont waste your time, its a cool toy, and you're excited...but what u got wont work.
I am glad so many people know so much about what won't work without ever trying it.
So I will go off and do my Multi-color led test (btw I have 10 of them for 1 plant)
So if it works I will come back and let you guys know (with proof) and if it doesn't I will keep looking outside the box for Ideas, I just won't bring them up here,

Don't pout
I've assisted in experimental LED grow ops at my university, same results everytime. The plants grew, but not as well. A ton of other growers had the same results on this forum.
Please make a journal of your experiment and prove everyone wrong.
LOL don't pout LOL
I was looking for input from some of those growers and all I got was "you are wasting your time" from 4 or 5 people. Someone telling me it is a waste of time and someone saying "I have seen X, this is why it won't work" is a different story.
Would you quit school if someone said it is a waste of time?

well on the colors of light spectrum there have been millions spent by nasa on researching the led colors to use for gardens for future space and plant colonies. You can also look at pretty much any hid light bulb package and see the optimum spectrums the light is designed after research for each stage of growth. They even mixed spectrums to get optimum growth which is what an enhanced spectrum bulb is. Green lights are use to go into grow room during the dark period as the green spectrum is not used by the plant there for it does not disrupt the dark cycle it has no impact.Your main 2 will be blue and red as the most impoirtant with trace amount of yellow or white spectrums add very little extar boost if any.Im not gonna bash them but after decades of scientific study and millions of dollars spent on research of light wave color usage its pretty much been mapped and shown what colors do what..Just curious you spent $30 x10 so $300 when you could have gotten 3 400 watt digital lights or 2 600 watt digital HID lights.why not get those?

please tell me a brand name, this would go great with my 1000w hydrofarm hps, cant seem to find anything but the bulb for that price tho...thx

I get my 1000 watt ballast on ebay for $45 delivered

My original post with my own research on the subject and the pics of leds that i thought would work and in actual agreement with you that 5 watt leds if used in the correct wavelengths work well.
I researched them for 3 months,extensively.
Blue and red are all you need,but feel free to look around.
Sorry if my post appeared to be negative but that wasn't its intention

I think that my post was perfectly reasonable and unbiased truthThe 5watt leds are good for growing but they are still to expensive at the moment.
They emit a whole lot more light than you would expect them to.
You need to purchase proper 5 watt leds though that have the correct wavelengths for a successful grow.
These 5watt leds are in my opinion the only leds capable of giving a great grow.
If you have the money and the time to use these 5 watt leds to grow with i reckon you would need at least 4 blue and 4 red per plant.
Here are the ones that i was going to use when i researched them and the pics i have posted are the correct wavelengths.
You can also add warm white or just white as well if you want to.
I would recommend using blue and red at the same time all the way through the grow

Natmoon, thank you for the info I did not take your posts as neg.
FilthyFletch: I know you have had that light bulb go off at least once and said that would be so cool if it worked????
I did not buy these for growing I bought these lights for landscaping my house and 1100 gal khoi pond. but once I saw them they looked so perfect for growing, so I will try them. and when you buy 10 on ebay they coast about 150 and I have a 400 hps and a 400w MH already

What do you guys think of LED with CFL for keeping mothers and clones?
