What Ian said above is quite true. An emulsion with all finals in it for keeping is hard to sensitize. OTOH, the Ammonia will move things along. OTOH again, Ammonia, as a silver halide solvent can have speed effects of its own. So, this is a really hard call. Try making an exposure through a green filter using film before and after sensitization. One will be blank and the other should have some image.
