I think my mother in law might have done it for vegetable seeds a few years ago? I seem to recall that they sprouted well but didn't transition easily to outside. Sorry I can't remember more than that but I can ask her if she has done more with it since.

I used both red plastic and red leds to germinate rose seeds. I am not familiar with using red light for rooting.

I have some posts on this subject on the rose hybridizers web page, but that page seems to be down.

Considerations when setting up your germination red light experiments

Why use a red filter? Answer - The original scientific paper , J. Amer. Soc. Hort Sci.,volume 120, pages 953-955, (1995) by Y. Yambe, K. Takeno, and T. Saito tested white light provided by cool white fluorescent tubes, red light provided by a red cellophane sheet and blue light provided by a blue cellophane sheet. The red filtered light provided the highest percentage (around 38 to 58%), white light provided a germination percentage of around 15 to 28 %. It appears that blue light is absorbed by both forms of the phytochrome and is to be avoided. This is the reason for the red filter.

The following are from the book "Seeds" by Carol C. Baskin and Jerry M. Baskin, Academic Press, 1998, pages 14 and 15.
"Cool white fluorescent tubes are a better light source for germination studies than incandescent light bulbs. Cool white fluorescent tubes emit considerable red but very little far-red (Toole, 1963)...."

".... This means that one or two 20-W cool white fluorescent tubes 15-20 cm above each incubator shelf will provide enough light for germination, if the lights are on for several hours each day."

"...light of "...almost any quality inhibits germination if applied at high irradiances for sustained periods: (Roberts Et al., 1987). The maximum photon dose (=incident photon flux area density X duration of exposure) of light that can be given to seeds without inhibition of germination varies with the species (Ellis et al., 1986a) and among seeds of the same species (Ellis et al., 1986b)."

"Photoperiod, potassium nitrate, and temperature may also influence the maximum photon dose for promotion or inhibition of germination."

"Because the high irradiance reaction overrides the reversible phytochrome reactions (Borthwick et al., 1969; Bartley and Frankland, 1982), exposure to continuous light during germination tests may inhibit germination.."

Thus it appears that one should not leave the lights on continuously. I now use timers that keep the lights on during the day but shut them off at night.

I did try both 24 hours and the 12 hours and did seem to get slightly better germination with the 12 hour on experiment. However, turning the lights off also probably produced a cooling effect which also may have been the cause of the slight increase in germination as compared to the 24 hour on experiment.
