which is better to grow HC emersed or not? NEED HELP!

**sapphire28** · 21st Jan 2009, 16:51

i've been having trouble growing my HC for a month now coz they all eventually turn brownish and die. i've read that some tried growing their HC emersed and have been successful..

is it better to grow HC emersed or not? any tips on how to get them grow faster? i just started my nano tank last november.

suggest to grow emerse, try them my self with success.

emerse is much easier it seems..
i heard rumors HC was orginally a land plant making it strive better out of water...
but i am currently growing them submerse
its gonna take a long time and more hard work to get them to adapt..
next project to go emerse for me

Hi bros, seems like HC is very popular among aquascaping. May I know what is the common name for HC. Do LFS sell them? What are the condition requirements for HC? Thanks in advance.

common name is HC, scientific name Hemianthus callitrichoides 'cuba'

I'm growing it emersed too. But just started 2 days ago. Will see how fast, or slow it will grow.

Agree with robert, emmersed form has a higher chance of success. But I grew them for 3-4 months before I flooded the tank. You can check my 1FT Nano HC links in my signature.

I grem them about one month, but 110W for 2x1x1.2 ft tank

Its a emerse, so no need to worry about algae, put as much as light as possible

110W!

Did u turn it on 24hrs?

Btw, for nano tank setup of HC, is it really necessary for CO2? Dun have can anot? Are those CO2 tablets good enuff?

I jus started to grow them emersed abt a week ago....doing quite well.

of course not, plant also need to sleep. I turn on 8.30am to 6.30pm. If you happen to read AquaJournal online article on the light, plants seems to stop photosynthesis after 10 hours even though the light still on.

In my opinion CO2 is part of the helping element to convert HC from emerse to submerse. I fail growing HC emerse twice, it melt 1 week after fill in the water. I do not pump CO2 and use excel instead because it is in small tank 30x16x18cm. The third try is using 2ft tank and CO2 injection way about 30ppm. My drop checker show yellow. First 1 month no fish so it is ok overdose CO2.

uhm, how do you provide CO2 if it's grown emersed? i've never grown anything emersed before so i kinda need some help here.

thanks for all your replies!

There are lots of CO2 in the atmosphere, no need to worry about CO2

emersed for me... grows much better as compared to my submersed attempts... its much easier to maintain afterward too...

**edmund77** · 1st Jun 2009, 22:53

what is emersed and sudmersed?i planing to plant HC too.which is better to cover the bay of the tank?

**Shadow** · 2nd Jun 2009, 08:58

emerse = only its root under water
submerse = everything under water

**seanaw** · 25th Jun 2009, 16:28

been tryin to grow hc in my 422 but seem the roots cant hold to the soil..

**madnugget** · 25th Jun 2009, 17:05

are you trying submerse or emerse?

**shrimppaste** · 26th Jun 2009, 02:19

Hi,

This is timely!! I was reading Tom Barr's method of "Dry Starting" a tank. Meaning growing the foreground plants before adding water and the background plants. However, I have a few questions regarding this.

1. By foreground plant, does it mean crypts as well?
2. For plants that requires lower temperature (For example japanese hairgrass etc.), will this method work? I mean we cannot use a chiller with a dry tank.

Thank you so much and sorry for slightly straying from the original posting.
