"What we are growing with LED is an articifial plant"

I don't know whether to laugh or facepalm over this statement.

"but is any light inhibitory?"

Yes. You want to inhibit flower growth? Hit cannabis with any amount of lilght that will trigger photosynthesis. You wish to inhibit overall plant growth? Use an excess of green and yellow for terrestrial plants. We've known about this for at LEAST 50 years, the studies are published and out there.

"Yes but the plants see all of those wavelenths as different unlike us. "

Plants don't see, period. They respond by phytochemical processes. Light is light is light is light, period. Photons are photons, there is nothing special as you are attempting to point out, it's just that plain and simple. Get to my level in optical physics and photobiology and I think you'll be racing to edit most of your posts.
