Evo ti citat od Barra:
I've had L inciliata blood red also, it's a frigging weed though. I hate the plant due to the insane rates of growth. Lower NO3 never did that much, I was the one that started suggesting it in the first place and told folks why back in the 1990's.
Basically the Chl is a very rich Nitrogen pigment and it's green in color. No N supply or a limited amount, and you get less Chl, this means you get less light gathering and less growth as a result, as well as less CO2 uptake since N is also heavy in the enzyme that fixes CO2........
This is a two edge sword.
So with limiting N, you limit Chl, so there is less green.
However, the red color stays the same if.........you also have good/great CO2.
Remember that limiting N limits all the enzymes as well, and this means less ability to fix CO2 and less ability to capture light. so you end up needing more light and more CO2 to compensate for this limitation.
Additionally now you have dose more carefully and have higher light and higher CO2.
Why bother?
I think it's easy to do for a temporary picture, etc, open house, but it is a bad method since it is reducing the stability, is a sign of stress in plants, not health, can increase the likelihood of bottoming out the N.
Reducing N does slow growth, but does so at a metabolic cost.
It reduces Chl, and helps show the red pigments. It does not increase the red pigments however.
This is my tank right now with some red plants. the L peruensis/granulosus is pretty red/burgandy, the M turb is pretty coppery, even the Green R macrandra is semi red, there's a shaded stem of the normal R macrandra in there.
Lots of well feed fish, 1.8w/gal of T5 and 24" deep tank, and I dose 30ppm a week of KNO3, plus.........I have another source for N, the ADA AS on top of that.

Ono što sam i napisao, čovjek ima 30 ppm KNO3 i rekao je da ga dodaje + što ima puno riba koje ga proizvode u dodatnoj količini. Glavni faktor za lijepo crvene biljke navodi u par postova prije i govori općenito odnosu prema akvaristici. Po meni je glavni čimbenik svakako svijetlo i co2, nakon toga bih stavio česte izmjene vode, pa makro i mikroelemente. Primjetio sam da kod mene crvene biljke najbolje uspijevaju u podlozi gdje imam flourita, a on je opet prepun željeza, tako da mislim da željezo ima isto tako jako veliku funkciju u tome svemu.
