Advice on cycling with plants?

Currently cycling a new planted shrimp tank, co2 and high lighting all that jazz. Should I add plants while the tank is still cycling? I'm using fluval stratum, so hypothetically that should provide all the necessary nutrients for the time being. Furthermore, should I dose any ammonia in the tank? Would this help cycle the tank faster? Currently there's no real source of ammonia, as there's no livestock or decaying plant matter.
