Still wondering, here ya go:

"Rauber Enhancement is the response between two saturating spectrum durations that occur within ninety minutes of each other, where the responses based on each time duration, rather than a response to an intermediate combination of the spectrum based on the wattages of the two spectrums." (from chapter 3 of ā??Photosynthetic Articifial Darkness, Rauber Enhancement, and Rauber Enhanced PAD. 1st Edition AKA: The PAD Manual. Copyrighted 2009 Shawn Rauber, as a representative of Temporal Photonics and of the author, I have express rights to reproduce this citation of the authorā??s copyrighted work.)

It may not sound like much, but it solves every gripe I ever heard about indoor lighting, and is a God Send to LED growers.

"PAD Manuals" will be available on eBay shortly they are currently converting from CD to paperback, due to a CD production flaw (resulting in a recall of the first batch of disks, disk will also be available in the future ~ slight delay).

Sorry for the delay, but I'm rolling with the random as it comes.

I should be back online regularly to answer your questions as best I can within the consent of the author.

Take Care, Sal.
