My dwarf sag stayed under 6 inches until about a month ago, when it exploded. I just looked over and noticed one of the leaves has hit the surface on my 50 gal, so about 15 inches! It's grown in so thick it has become the 'shrimp forest', but unless you stay on top of it it'll grow upwards and onwards.dwarf sag grows like crazy. But there is some speculation about how "dwarf" it is
I have dwarf sag in a 2 gallon cookie jar and its doing good but, a little tall for what I was going after.
Chyrol you suggestion of moss tied to a mesh sounds good. My question would be can I bury the mesh under the substrate of leave it above?
Thanks everyone for your comments.
