  • Proserpinaca palustris "Cuba"

    I've recently aqquired some stems of this gorgeous plant. The only thing I haven't figured out is how to maintain that deep red color. Some say low NO3, others say 10-20ppm of Mg. I have no clue. (and I'm hesitant to experiment since my planted tank is still growing in)

    I'm currently using a bit low lightning for this plant, or so I've been told. 4x 24w T5HO. It's a Giesemann fixture and it also has a 150W MH that I'm not using atm.

    Any help appreciated.

    Red Plants: Low NO3, I Do Not Think So


    Not much of a believer in the whole low NO3 thing, I have found that keeping the plants in ther comfort range is best, with some “red” plants there are simply a lot of variants.

    I have not had much experience with “mermaid weed,” a little quick research indicates it likes brighter conditions, which I have found is often code for give it some space… I am not sure it is really nessacary to increase the lighting substantailly.:gw Increasing the lighting dramatically can have the affect of throwing off the system, as you say you are in the "grow-in" phase and apparently happy with the results.

    This weed also takes a little time to settle in and make itself at home.

    Tell us your experience as you progress.

      It's been in there for about 3 weeks now. It was rather shabby when I got it, leaves all curled. Great color, though!

      When I got it:


      I'll give it some time. It has been moved around aswell, so that might have some impact on it.
