do i need substrate to grow a lawn

  • We are currently upgrading MFK. thanks! -neo
I think it would be easier with substrate.
 
Or a grid of small sticks like bamboo skewers to anchor them to.
 
My ex-girlfriend cut her lawn so she wouldn't have a substrate.
 
Howdy,

You can weigh it down onto a bare bottom with a few rocks. It will attach to the glass and grow. java moss does not need substrate.

It's much easier if you attach it to something. A roling moss gathers no stones. Or something on that order.
