Red plants without High Light and High co2

[Rohanz21]

Is it possible to get red coloration(not deep but descent red)in plants without using high co2 and high light?

You can try it using low NO3, effectively less than 5 ppm. But thay's awfully close to a deficiency, which will give you other problems.

Yes, A reineckii has done very well for me in the past in a non CO2 tank.

@ Dutchy & @Tom

Actually i have rotala indica which were green initially.Used PMDD(with a bit high phosphate) dosing which resulted in pinkish coloration of the rotala.Meantime i gave diy co2.

But when i removed the co2 and started to use EI dosing the pinkish coloration faded a bit.

What you think has actually happened?

[dutchy]

Probably you already had low NO3. When you started to use EI, NO3 levels rose and the plant went green again. Unlike what we like to believe, green is actually a colour that the plant has when it's healthier. Red is a starvation colour

This was during EI dosing.Presently the color faded.

I thought red coloration require some special maintenance :P

Thaty means coloration other than green is the symptom of nutrient deficiency ?

Here in Costa Rica most people have non-co2 because regs are unaffordable for most hobbyists, with enough light red plants are red.

How much and what light(color temp.) you use?

certain specimens of tiger lotus have a very deep red colouration that isn't mottled with any green. other plants i have seen is ludwiga ovalis, with lower light you'll need the bottom of the stems to be out of view because they'll be straggly

I have Rotala indicia in my non co2 low light tank and it does great. The tips get the red when they are close to the surface where the light is a bit higher! I have b.l. and n.l. ludwigia also in there and they do great as well.
