1 w/l is plenty of light, furcata is growing for me under less than half that amount. What is it doing exactly? I mean is it melting, shedding, stunting, turning pale..... it could be many things.
Why are your NO3 and PO4 so high? Makes me wonder if something is missing in your tank and therefore plants are not growing well and consuming enough macros. What is your FE level? What is your water change and fertilization schedule?
The more info you give us the easier it will be to find the cause.
i dose macro's once a week and its not melting but its in the same condition as it arrived to me and all the others are growing faster
i dont check the iron level
w/c - 10% each week
fert - kno3 on daily basis
fe gluconate on daily basis
and macros and P after w/c - once a week
sorry mr. podio but i do use csm+b also... forgot to mension that. i moved it to another location and it look promissing though
could it b because all the substrate occupied by the glosso and dont give any place for the furcata to anchor? - i tot that cabomba species dont need to much place for their roots though cause they take the nutrients from the water column
its not sick but its not growing for 3 week (since i got it) - im afraid to trim its "head" and loose the whole plant cause i got it from thailand and cant get another one here, its only 2.5-5 inches long - can i cut it?
I think you need to do 50% weekly water changes, then start dosing KNO3/PO4.
Mine grows about 15-25cm a week.
From the looks of it, it seems like you are actually NO3 deficient.
Even if your test kits say you are not. The growth pattern there tells more than than some cheapy NO3 test kit.
If there is CO2/light/traces, PO4 etc, then the plant should not look like that at all, unless poor NO3.
Try the water change and then dose some KNO3 back and see.
my name is baruch mor n im looking for blyxa jap. for a VERY LONG TIME here in israel without good results... would u send me a few plants to start with please? i would pay everything , all the shipping and the price of the plants even if they will die in their way ......... i am an foriegn exchange trader in a bank - so its not a problem for me to transfer u the money everywhere in the world...
and if its ok , i would like a few stems of rotala macrandra too.
thanks and have a good day
Thanks Tom For explaining that to me. I thought compressed internodes..like growing reg. houseplants....equals good light. It's when you have too low of a light that it leads to larger internodal spacing.
Interesting symptoms of N def. Hopefully I can catch your article!
I can send you some, but realize that both countries have become really anal about imports and mailing. So it might come cooked or might not makes it for a few days. DHL is one of the better methods.
Sending stem plants is tough. They often melt due to heat.
Short internoldal spacing can be from a few things. In this case, the intense red color is nice, but the slow growth and close internodes is not a sign of good fast growth and that something is slowing the plant down.
Cabombas are very fast growing weeds and tend to be very good competitors for nitrogen.
Therefore it's unlikely that the rate of N being added is very high. N is the main driving nutrient for biomass growth after CO2/Light.
PO4 on the other can be low and plant biomass maybe unaffected in many cases. Some plants are different but Cabombas are fast growers and easy to talk about.
