I have grown hc emersed and submersed it it loses some of its leaves but doesn t take forever to grow back.
Hc carpet emersed.
Mosses in particular have very different emersed structures and can be quite cool looking.
Majority in the trade or aquaria market sells cuba in the emersed form and it has roundish leaves.
This video is of my little h.
This method should work well for all mosses most grasses and most other carpet plants like hemianthus callitrichoides and glossostigma elatinoides.
Its also known as pearl weed.
I don t think emersed growth works as well for hairgrass in terms of getting a very thick coverage like with hc.
Light will be medium high.
Glosso will be a better choice if it is frst time trying.
Sometimes you can see the tiny white flowers in the axils.
But it does demonstrate that high light no co2 doesn t always translate into an automatic algae fest that is if the plants are growing well.
Just started my hc carpet 1 5week ago going to complete the emerse to submerge stage.
In the submersed form it looks almost same as an emersed form with cushion like growth or low carpet.
It will carpet but the leaves are a totally different shape than dwarf baby tears hemianthus callitrichoides pictures below hemianthus micranthemoides giant baby tears pearlweed hm hemianthus callitrichoides dwarf baby tears hc hope that helps.
Hey all the title says it all.
Growing hc also need luck some can grow it without cold water but some with cold water also cannot make them flourish.
All fine in about a week or 2.
Another two weeks and i expect it will be covered.
17 days from planting three small 4x4cm pots of hc.
It s almost tempted me to start a palaudarium.
As for hc you will need high light and lower temp so that it will grow better.
The carpet of glossostigma in the picture below is grown using 150w metal halides hung 2 feet above the tank.
Cuba has smaller leaves and a bit narrower.
Imo it s all about lighting and co2.
This light level is probably excessive.
However i think the initial 1 month of being established when emersed helped a lot and prevented algae issues with the hairgrass.
