You might get a little taller working on your posture maybe some back exercises but only 1/2” or so. You certainly can grow lemons anywhere in the world if you keep them indoors. People have been hybridizing citrus for centuries, I think all of the edible citrus is the result of hybrids but in all of that time, this is as far as it has come. A few more centuries who knows, maybe.
