Growing Blyxa without substrate

[charlie]

Do you guys think it`s possible to grow healthy Bylxa Japonica & have it propagate without any substrate?
Really want to hear your views on this

[wolfiewill]

Ok, what do you mean - without substrate? Like a epiphyte on a log? Or floating? I'm confused..... again.

Stuck in the crevice of rocks

[wolfiewill]

You mean 'coarse gravel'? That sounds like a substrate.... sort of. But no, I've never done that. I got mine from you and did what you told me to do with it. And it's now one of my favourite plants. And, thanks for that, Errol.

No like stuck in between rocks from a rock pile like you would with Java fern, think it`s possible?

I think it may.  The root systems on this stuff is huge.  I have it growing between small rocks with a little large coarse gravel between. the roots go everywhere. I occasionally trim the roots to keep them out of view.  the stuff is a weed
