Same problem also with Tropica 12grow format... All the stems began to melt near the bottom. In the period of two weeks they all went away even if the damaged stem was discarded and then replanted. However the plant was bought in September, my LFS was moving during the summer and I really suspect the plant was not really kept in the better conditions until I bought it (move + high temperatures + low plant turnover in that period = bad plant). Although I've read quite a lot of times this same problem with this species, TBH I have no idea if this is the real problem. Other plants (emersed and 12grow format) were bought that day and did ok.
Anyone knows if it is a sensitive plant to water parameters, light conditions, etc.?

Good morning,
As i have sent a claim to Tropica arguing about this issue and mentioning also those thousands of us whom suffer with this plant, so they could see that it was not a problem of my own, i received an answer from a Tropica high specialist, who takes care of all their trial tanks and scapes, who tests new species etc.

First i´d like to congratulate Tropica for their care in answer a claim and do care about our problems. That is a High Positive note for the company showing respect for their costumers. At list the´re not like ADA and others who don´t give a damn to what we say. We claim, receive a "READ RECEIPT NOTE" but no answer at all...

I also sent them the entire SET UP of my aqua and photos of the other plants so they could do a better analisys.

And.. even them can´t come up with a solution and that is something i perfectly understand. Too many factors surround the subject. Even them we´re quite suprised of what happen. I thing they didn´t knew at all about this. They say my aqua parameters are quite as their´s.
Only two differences: Temperature and KH or if unless the plant material (= 1-2-Grow! cup) has been stored for much too long in the pet shop…(this we never know..)

They say that all their plants are cultivated in 24º degrees and 5 KH no matter species. Well.. yesterday i put my aqua in 24 degrees (as it was in 27/28 before) and let me tell you..i didn´t imagine that this 3 or 4 degrees could do such a diference but it does.
Formerly i put my hand in the aqua and i felt hot water. Now i put my hand in there and there´s a lot of difference.. it´s not hot anymore but also not that cold that you feel uncorfortable. It´s cosy..

So this is the only change i made as for the KH i can´t do a thing..

Let´s see if the stems that are surviving live long.. if not i´m going to try again directly (sametime using the propagator love this ideia ), in the tank but now with this 24 degrees. Somehow i do believe that this issue of temperature might be the cause.. as the plants are in the cups a week or two and certainly not at 27/28 degrees and this heat shock might be the cause. Not all plants suffers as equal but i did have this issue once with the Staurogyne to.

Other important aspect that we should take note for the future:

They only use light-sources of 6500 Kelvin, since this has proven to satisfy both plants and colour-appearance for the viewer.

For a matter of respect i won´t copy their answer to here.
