I see the desire for red plants, but it's an interesting concept. hum.... Any other reason why you'd want to use it? Aidan, I realise CPs do not want any additions to thier soil, but could the dye actually hurt/kill them? I would by no means actually try for fear of killing the few little guys I have, but it would be an interesting study I think. But not by me of course  |

Something slightly related regarding water and red colouring...any idea if there are any studies into chemically influencing the production of the red anthocyanins? I know exposure to sunlight tends to create the red colouration, but any idea if there are chemical reactions that could achieve the same thing?

I doubt there are any studies but there are some growers who brew up infusions of peat to water (Sarracenia) plants with, assuming that tannins will deepen colouration.

This is about some other posts... When the people said about red coloration in plants... it's not for the plants. I want Red Coloration in the water

The problem is that the food color will be absorbed by the plants. If you haven't done it in a classroom at sometime in your life take a sprig of celery with leaves or a white carnation and put the cut end of the stalk into a glass of water dyed with food coloring. In a short time the dye should transport and be visible in the leaves or petals.
The same thing will most likely happen to your CPs and the dye may not have a beneficial effect on your plants.
Maybe some red Daphnia in your trays? If you add some aquatic Utricularia it will have something to eat.
