Which is why I said algae. Imagine a closed pod that will take in martian atmosphere and release oxygen from time to time. It's seeded with algae and sewage from earth for nitrogen. You just leave it there and forget about it. Start by sending one pod, then 2, then 4, then 8, 16, 32, 64 and eventually martian atmosphere will be full of oxygen and the pods will be opened, once they're opened the algae can colonize the martian surface
