Hello and welcome to the forum!
Do you know what level (ppm), your ammonia is at now?
A common mistake, when doing an ammonia/fishless cycle is add to much ammonia and kill or stall the cycle.
I would bump the ammonia up to 3-4 ppm, and not add anymore ammonia, till the tank starts it's cycle process. If you take a reading, and notice that there has been a significant drop in ammonia, that is when it is time to start adding ammonia daily. This can take a couple weeks. The tank might just sit at 3-4 ppm for a while, then one day, yea, the ammonia is dropping.
I added ammonia a few times a day, during my fishless cycle. In theory, its better to have a constant supply of ammonia, to feed the cycle. If you do not have the time to do this, a once a day feeding will also work.
