If you planted it densely and added only a few fish to begin with, you can get around the whole cycling thing. The first couple fish would produce little ammonia, which would be taken up by the plants and not the biological filter. By slowly increasing the number of fish you have, you will eventually reach a point where the fish will produce slightly more ammonia then the plants can take up right away. A biological filter will start form and you won't have high ammonia or nitrite, because the plants are taking up the excess. You just have to be careful how many fish you add, too many and you will have high ammonia and nitrite.
You can also cycle a tank instantly by adding mature filter media at the same time you add fish.
