but the red and blue looks better
Outside the photoperiod my light is on but somewhat dimmed
Not really, it's too dim. I doubt it's even anywhere near the light compensation point, for instance.Surely red/blue light is utilised by the plants for photosynthesis, so the photo period is just extended.
The goldfish Carassius auratus has tetrachromatic color vision it can see in the red, green, blue, and UV regions of the spectrum.Would I be correct in thinking that fish 'see' in a much wider spectrum than we do.
Does this apply to other fish, or is there little or no research on other fish species.tetrachromatic color vision
What about growlux tank lights and their equivalents in LEDs as used in hydroponics. These match the photosynthesis absorption spectra. Its dim to us but is it dim to plants.Not really, it's too dim
I think it's probably more common than was thought to be. Apparently a wide range of fish species posses this adaptation https://en.wikipedia.org/wiki/Vision_in_fishesDoes this apply to other fish, or is there little or no research on other fish species.
I think spectrum matters to lifecycle and growth morphology, any white light is full spectrum, as far as plants and humans are concerned. The photosynthetically active spectrum and the visual spectrum are one and the same give or take a few nm; a happy coincidence of evolution.What about growlux tank lights and their equivalents in LEDs as used in hydroponics. These match the photosynthesis absorption spectra. Its dim to us but is it dim to plants.
