> With air cooling this is much more difficult
To my understanding, DCs use air conditioning systems for cooling. These are already heat pumps - why would it be more difficult to just pump that heat into district heating instead of outside air?

Economically the greenhouse would have a distinct advantage of using free heat, and already having enough electricity wired nearby.
This, of course, only makes sense during cold seasons, or somewhere like Alaska or Sweden. During hot months, 40-50°C of heat seem completely useless.
Maybe next to a sea such waste heat could help evaporatively desalinate seawater, while cooling back to reusable temperatures.
