i'm not there, so i cant say definitively, but i would wager that it would be completely fine.... the medical card covers the person it was issued to, not the household that they live in... so if two people in the same house were issued med cards, then i would assume that the limit would be doubled, as there are two of you, but i do not know if they would allow you to combine your grows.... but given the whole "caretaker" system, I dont see how it could be illegal.
