Is that sufficient with no requirement for further earthing?
That comment is s bit moot for this OP. It's already been done, and there is no harm in it being an RCD socket even if it doesn't need to be. In fact, there's a chance (although no certainty) that a fault in the greenhouse might ('conveniently'!) trip the greenhouse RCD but not the house one (if there is one).You have used an RCD socket! Is this circuit not already RCD protected in your CU? If it is you don't need an RCD socket.

I tend to wonder if you need some sort of cable restraint, after all your only glanded into a plastic box.
