  We study $g$-vector cones in a cluster algebra defined from a weighted
orbifold of rank $n$ introduced by Felikson, Shapiro and Tumarkin. We determine
the closure of the union of the $g$-vector cones. It is equal to $\mathbb{R}^n$
except for a weighted orbifold with empty boundary and exactly one puncture, in
which case it is equal to the half space of a certain explicit hyperplane in
$\mathbb{R}^n$.
