GB what's up? Have you read the PAD manual? If not you might want to give it a quick read. Unfortunately both of these treads were done before we could read the PAD manual. So you see SID being used in the mix (because we didn't know better). But Rauber's Enhanced 24hr flowering method uses no SID. Just thought I would put that out there..:thumbsup:

As far as using white led's as the PAL lighting in a PAD lighting setup.. I would think you could.. The results might be like using 630nm instead of 660nm. Yes 630nm will work for PAD lighting BUT 660nm hits the bulls eye. I've done the 24hr flowering using an HPS and a MH as my PAL lighting, I think the MH did a better job in my PAD setup.

Hopefully Sal will post a response.

P.S. There is also a couple of treads in the advanced section on this site. The treads are UV an experiment and HID time factor manipulation and another one I can't seem to remember at this time sorry, but if you look you will be able to find it.
