  The lowest dimensional gluon condensate $G_2$ is analysed at finite
temperature and chemical potential using a bottom/up holographic model of QCD.
Starting from the free energy of the model, pressure, entropy and quark density
are obtained. Moreover, at zero chemical potential, the temporal and spatial
Wilson loops at low temperature are computed; they are related to the
(chromo-)electric and magnetic components of $G_2$, respectively.
