(addition talk on the white led) This will give me a much broader spectrum of light. Now I will still have a large amount of 660nm light with a smaller portion of 630nm light. In addition to that I plan on a second stage for my light consisting of UVa and 605-620nm and some deep red. Most likely 30-40 worth total(4watt(uv)30watts(610nm)6-10watts(730ish) that can be switched on around flowering time.

2 points, for enthusiasm.:thumbsup:
Love to see folks trying things for themselves.

And about multi-band lights?
There seems no need with Cannabis. 2 colors are quite adequate.

Then why hawk 5 band, new, and improved, "super" lights?
It's a crowded market, and most sheeple can be fooled most of the time.
So, if ONE blade gives a clean shave, 5 blade razors must be 5 times mo' betta' Ya?

Same marketing folks that sell us "better" eggs.
(I don't wish to know where they stuff the "extra" vitamins an' minerals so da eggs come out mo' betta.):wtf:

Any road, the fact that 2 colors will grow great bud, is the main advantage of LED growing.
Not gotta pay for generating colors that the plant does not use as efficiently.
(We pay 5X what mainlanders do for electricity.)

So, I no gonna "blind you wit science", no can.
I dunno too much science.
But I do know good buds.:jointsmile::stoned:

A little ~460nm. a bunch of 660nm. and healthy roots will grow buds like the sun. At least fo' me it does.
Can't guarantee your milage, of course, but I could not be happier with my well focussed dichroics.:thumbsup:

Please start a multiband thread and run a side by side with a multi and dichroic. I'll be watching with great interest.

Yer welcome, brah.
Them 2 pennies was burnin' a hole in me jeans anyway.
