Growing Hemianthus callitrichoides (HC)

[thengz]

Digging up an old thread here. Just wondering, has anyone been successful in growing the emersed HC submerged immediately without dry start method? If so, what are the water conditoins?

Currently I have CO2 in my tank, and temperature of water is around 28 degrees. The soild I'm using is the one sold by CRS Haven for shrimps.

Thus far, my HCs have been pearling, but probably only 1 pearl every one square cm of HC per day. Is that any measure for success? They have been in the tank for 5 days so far. So i'm hopeful.

Anyone out there that has tried, and succeded? How long does it take for the HC to start spreading?

you need a soil with high fert content, like ada amazonia, high light and co2 levels. If your HC is emersed, bubbling is normal at the beginning, but does not mean its doing well. Give it at least 2 weeks, you will know if it will succeed in your tank. Use drop checker to adjust the co2 levels. If requirements not met, they simply melt and its unsightly and hard to clear. Good luck.

Sure, many times . You need fertile soil and plenty of CO2. Try not to have any fauna like shrimps or anything that can uproot it, at least during first or two months.

Ai Carumba! That's going to be a problem, cause I won't be around to monitor the next 2 weeks. My mum would be helping me with the CO2, light, etc, during this period of time, but she probably can't make the decision on whether to clear the plants or not.

Looks like I might need to uproot them before I go on holiday. I'll monitor it for the next few days, if I don't see any progress in terms of spreading or if the plants start growing upwards, I'll probably get rid of them and start again on another tank when I'm back. This tank they are in are 2 weeks or so into their cycling process.

Yep, didn't put in any shrimps or other fauna yet. Will probably do that in another 3 weeks when I'm back from my hols.

Mine is bubbling even when i am using 1.5 BPS...
plus end of photo period got some larger bubbles stick on the leaves...

Actually thought never bubble thinking it is from my boyu diffuser, until i took a closer look at the intake end.

Waiting for my LED strips for DIY moonlight.

Oooh... Nice, you also threw your emersed HCs in straight away? Actually my main concern now is if it can survive through the next 3 weeks. If it can, I would just let it grow while I go on holiday. If the likelihood is that it would die, I'll take them out before I go on my holiday so that it won't disrupt the cycling of my tank.

I've had some growth in dsm, but just added water since I'm growing hc emersed with my potted plants outside.

If your conditions are good ( I mean with chiller/fan + co2) coupled with the cool weather. Why not give it a go?

[Kiatster]

Felix, what i meant was that if the plant is grown dry before putting it into the tank, it will still bubble but may not be because its doing well. I tried that before and after awhile it stopped bubbling and then melted. But once it settles down then if 1.5bps is sufficient the it will bubble too. It really depends on your plant load too. Thus i recommended co2 indicator for better gauge rather than just bps.

now i get what you mean...
my Co2 is quite saturated with my indicator showing yellow(still a slight tint of green) all the time. Never had HC before so i am observing closely and try to learn more.

I am after a 60% plus HC lawn since i am starting, learning a step at a time before i start doing more rockscapes.

Going to start HC ahead before i scape my tank since it takes like 1-2 months.
going to grow in another harvester tank and move them into new tank onces mature

1. Getting my new amazonia soil -> do i need to add more nutrients? like power sand for base?
2. Using dry start method -> so get submerged or emmersed HC ? confused
3. Going to use excel to supplement CO2 during wet soil, no budget for CO2 tank.. go low tec
4. light interval 12 hrs > 4-1-4-1-4
9am - 1am , 1 hr break
2pm - 6pm, 1 hr break,
7pm - 11pm
trying to give half day of light 12 hrs
5. temp with fan 27 deg

Did i miss any steps?

Darn, the prognosis is no good. I'm starting to see yellowing leaves and dark/dull green leaves. I'm guessing I might have to pull them out before I go for my holiday.

And ya, Kiatster is right, I have pearling first two or 3 days. But last night, no pearling. Looks like it's going down the gutter, will probably increase the CO2 for the next 3 days, if it still doesn't work, I'll take it out, and try again when I return for my hols. Probably try doing a DSM method on a small tank or something.

Holy cow marimo! I just saw the pictures of your nano tank in the gallery. Very inspired by it. Will probably want to try something like that in the future.

What plants/soil/rocks did you use? And what's the method?

[felix_fx2]

You trying to max out growth rate during DSM? (i would prefer 4-1.5-4-1.5-4)

Is this the harvest tank that is only DSM? DSM is emmersed conditions.
If growing a harvester then transferring (DSM or directly submersed), you understand the work involved correct?

i've never used powersand so far, if your budget allows it would reap benefits.

this is my 50cents

err which nano ?

You trying to max out growth rate during DSM?

hah ya , need them to creep during drystart
then most likely going to transfer them into tank and submerge them with daily excel
not sure if they will melt

[thengz]

err which nano ?

More like mini. The one pictured with a 50 cents coin. Looks like its only 15cm or so in diameter.

[marimo]

Oic there is my thread.
its actually much smaller .. the terrian about 6-7 cm wide

I did same before. After I changed all my t5 tubes. Growth seen is very slow.

Do try it out & share details.

[marimo]

yes will try .. getting my soil soon
any scoop of HC to spare? should get emmerse form? like from C328?

[SeVenZ]

Just checking if my hc are not dying but they are not crawling also, what can I do ? It's been in the tank for like 1 mths plus. But it's not covering anything at all? Still looks the same when I planted it.
Ada Amazonia soil
Excel daily
Potassium every other day

The rest of my plants are doing quite. Most have taken root and grown mad high but my hc have not move a single bit . Want to carpet my fore ground with it hopefully

C328 good. Much thicker growth for emersed then I can grow lol.
