XFree86 is a free and open-source implementation of the X Window System (X11) that provides a graphical user interface for Unix-like operating systems. While it is no longer the primary X11 server for most Linux distributions, it still has a dedicated user base and can be used as an alternative to X.Org Server or Wayland.

XfreeHG succeeds exactly where it aims to: it makes indoor growing accessible, attractive, and discreet. It is a high-quality product that solves the specific problem of growing in a living space without making it look like a laboratory. While the price is steep, the quality of the components and the engineering justify the cost for the right user.
