    The isothermal growth process of the smectic-C phase of 8DBH from the isotropic melt was experimentally investigated for a conventional calamitic mesogen with respect to quench depth, quench rate and cell gap. The observed growth structures exhibited a saturation fractal dimension of D=1.9, showing fractal growth in a conventional calamitic mesophase. Site percolation at the percolation threshold was suggested as the generic formation mechanism of the experimentally observed liquid crystalline textures. The time evolution of a growing texture was be simulated by halting the generic computer algorithm of multisite percolation after a varying number of iteration steps.
