LED spectrum and ratio for DIY

I am looking for input on what spectrum LEDs and ratio's to use to build both a veg light and flower light (separate lights). I have experience building LEDs for coral reef tanks but not for growing. Most of the commercial companies don't list this information so I was hoping you guys and gals could give me hand. Thanks in advance!

I am also interested in this since i ve got a 4(red):4(Orange):1(Blue) with 2watts LEDs with total 120w. I used this for both cycles. For flowering it is ok but for the vegetative state i would like to buy another more blue.
I found all blue LEDs in ebay (Running at 460mn) but since it can be costumised i was looking for ideas about ratio only for growing. Running at 1 watt LEDs 90watts overall.
Thank you.

Anyone have any advice or recommendations for spectrum and ratios for a veg and separate flower light? I can look at the commercial units but they don't say what ratios. Hopefully some of you DIY guys and gals can help out here.

I've had good luck with a mix of 4250-6250k white mixed with red and deep red with some farred.

1:2 ratio, white:red

My next light I get from you guys I'd really like to try a panel that has 4250k and 6250k in it, heavier on the 4250k though!

Instead of 5:4:5:1
(6250k: Red : Deep Red : Far Red)

I'd be interested in trying 2:2:1:4:5:1,
(4250k : 6250k : Royal Blue : Red : Deep Red : Far Red)

Maybe even 3:1:1:4:5:1....

Maybe you've already tested a similar panel?

I have had good luck with the same ratio!

can you make a single panel do both veg and flowering. if so what would be a good ratio. thinking about using 1w leds and about 30 or so. so run about 30w. only going to grow a single solo cup mmj plant. thinking about maybe 3:1:2 warm white 3200k cool white 10,000k and then a red not sure what red yet tho or maybe 3:1:1:1 and have two reds. let me know please

Check out this thread, SDS has some very interesting theories that have taught me a LOT.

can the plant grow even with the 2700k or warm white lights on or do they need to be off. ive only started and vegged under 6500k cfls never mixed spectrums.
