From previous research I found plants need ....and the sun gives

5.3% red light 723.18 nanometers
36.3% blue light 508.7 nanometers
58.3% yellow light 616 nanometers

So in Hz that would be

401.78 Hz at 5.3%
669.9 Hz at 36.3%
508.7 Hz at 58.3%

I do not know how to put that as a wave file but I can almost guaranty results

Sound stimulation for plant growth Hello people, I've though about placing two cheap computer speakers inside my grow room when I start with my clones... then hook-up a playback device (either CD player or cassette player) to these speakers. I though of playing classical music to the plants. I've heard/read that it helps. Upon two or three hours of research, I've found a couple of things::: There's a product/system out there called Sonic Bloom, which includes a CD/cassette with "melodies" and a foliar spray solution.
