good plants to use for a "grass" substrate and how to make it?
So I was talking to someone and the idea of just plants as the substrate.. like grass in a yard, would be really cool, so I decided I would try it, but I want an idea of how to make something like this. I was thinking of like getting some sort of like.. sorta liek the stuff on the end of the algae scrubber, and putting some seeds for this plant in it, growing it in a separate tank where I can have higher co2 and ammonia, then laying it out like turf. What would be a good plant to use for this, where can I get seeds, and where can I get material? Thanks!
