Can Hemianthus callitrichoides grow on black quartz?

[naresh666]

i am thinking of carpeting with HC but i am using black quartz?

[krabbie]

Heard that black quartz will cut the roots ... not sure if this is true cos I have never used it before.

[hebi]

i dont think so, maybe will grow but very slow, cause black quartz has no fert right? i use GEX soil also take a long time to spread when it is emmersed.

[naresh666]

how about bottom layer substrate then topped with black quartz? anyone tried?

[Shadow]

how thick is your quartz? HC root is quite short. I would suggest to forget about those quartz, unless you want to grow moss only.

the thing is i want to have a lawn.

and am now thinking of riccia

[Shadow]

mini riccia maybe?

[naresh666]
