That is what people say?
That is bullcrap!
I have high LED lighting and the tips of my Ammania sp. Bonsai AKA "True Rotala indica" are turning red and it is way down close to the substrate in the foreground.
My indica has pink about the top 3" of it, but it should be noted that I did this using two T8 bulbs on a ten G tank. Close
to the sub and in general. I now am having trouble getting any red in a Magenta which didn't have red but rather pink at
the top half when bought. Very suspicious of this BTW. As in could it have been indica which was pawned off as Magenta ?
The growth is great/was stunted from the LFS and had about 1-1.5" of it was 1/3rd the diameter but now from there up
is the same or better than the bottom diameter is. But a slight pink only. And one stem has no color other than green.
Had virtually no ferts when this plant put in but now as of two weekly doses it has Flourish Comprehensive for the Micro
and only Potassium Nitrate(have yet to receive the Potassium Phosphate) so far for the Macro.
It has a two bulb(on a ten yes) T5 light. And gets 1ml of Excel daily.
This is why I'm reading this thread...to get some RED color...LOL...
All the way to the substrate you say...great...one more plus I've read for the LED's which I've shyed away from since my
first one was a bummer(A Marineland Double Bright of course).
Thinking fairly hard about a Finnex Fuge Ray Planted+ though.
