I tried to grow it in sms with no luck. Through it in AS and it exploded.
I get it to turn purple with high light....Its very low growing and makes for a nice bush
I think it would be great for shrimp tanks.

SMS wasn't the reason it did not grow back then and it had to be some other factor that was overlooked or wasn't up to speed.

All I have in my tanks is SMS substrate and I grow much more difficult plants that that hygro sp. I even have the Najas sp Roraima growing well in SMS, so it's not some nutrient found only in the Roraima locale which aquasoil so happen to have that makes it grow them well

An inert substrate is never the issue if a plant dies or grows well (though it will make it easier to an extent if nutrient rich) it's all in the fert routine, Co2, water hardness...etc.

I have trouble with the CEC of sms, also I think TDS does not help this plant.

At what levels are you experiencing issues?

Well, considering we live in Florida and water comes from the aquifer.
We have liquid rock. Then you have sms which can steal the KH out of the water column.
Its a lot of work with sms, depending on your water source..
Now AS, or nutrient rich substrates seem to work very well and give very little hassle if any. As far as levels go, that's a very good question because we never test anything..

As far as I know a high CEC or cation exchange capacity substrate holds the ions of ammonium, potassium, calcium and magnesium in a non-leachable form making them available for plant roots....never heard it 'stealing' KH? Maybe someone can enlighten me here.....

High GH will not affect a true softwater sp. It is almost always suggested taht the values for GH to be low for softwater sp but I tested this to be untrue with many of the plants I have. 1 example of one such test was using very high GH (21 GH) with my Mato Grosso for 2 weeks to see the ill effects and there was none. KH on the other hand at only 5KH was an issue after 3 days.

Aquasoil does more 'stealing' of the KH than anything else out there but this is a good thing you want with the more difficult plants.

The highest TDS I used with this Hygro sp Roraima plant was 420ppm while doing some tests and it looked great. TDS will not cause a plant to die as long as we are in a realistic range. BTW I use TDS as a gauge of the water quality I like to maintain not to gauge plant success. Too many factors affect TDS the greatest one being Potassium (K2SO4) then CaSO4, CaCL2 then Mg....this is not including the waste from our fish, plants...etc.

Do you have soft water or use RO water? There is no way I would be able to keep any soft-water plant here in Florida, let alone in sms......

What is your water like out of the tap?
I guess I could ask my sister, she lives up in them parts..

SMS is not what is causing your issues, it seems to be high KH? Maybe some other component of your water purifier. High GH is not an issue with plants and neither is SMS.

I use 100% RO/DI with SMS with some of the most difficult plants in the hobby.

KH from my tap is 3~4KH and a GH of 8~12GH throughout the year. TDS ranges from 200~250ppm.

Yeah..That's what I thought..I could use RO water to grow these soft water plants. But I don't, so I only grow them in AS tanks.
If I were to try and grow them in my standard sms tanks, not good.
So..No its not sms, its a water quality issue and this I do know which in turn is why I use some tanks with AS or Gex..

Thanks, I need to start using a TDS meter and start some new methods in the future..

Cheers, Orlando

This is supported by the fact that mrk. had it do fine in SMS with what I can only assume is RO/DI water.

Also, having personally been to Mt. Roraima in Venezuela, I can convey that it is basically a tropical cloud forest and the small streams are all fed by rainwater (think crazy rock formations, 100% endemic amphibian species, crazy orchids and predatory plants...awesome place)....

Thanks Macclellan, this was my observation as well..Soft water from AS, or RO water is the issue at hand..

So in the end we now see that it was never the SMS causing the softwater plant death, the culprit is your hard (KH) water from the tap. Much better than earlier statements

I hope I can farm enough to share with everybody sometime soon.
Perhaps when the new tank is done I will have some left over.
