Wetting it once may not have been enough. If it dried out after the first day, mold would not have grown enough to be seen. Mold will begin to grow very quickly in wet conditions, but as soon as it dries out, it will stop.
Try putting the bread on a plate and allowing it to soak in the water. Since your cupboard is probably 70 degrees F or higher, the temperature is fine for growth.
Under the wet conditions, mold should be visible in three days or so and by one week, it should really look gross.

How quickly a bread will mold depends on several things, one being the "water activity" of the bread. An earlier Mad Scientist message gave the following information about bread molding: "Scientists measure "water activity", that is water that is not bound into the product, to help determine "shelf life", or how long a product can remain on the shelf and be edible. Pure water has an activity of 1.0 and 0 is bone dry. Bacteria generally stop growing at a water activity less than .91, but molds grow on drier foods, until the water activity drops below .81. Bread has a water activity of about .95. However, another factor about bread that determines how quickly it spoils is its pH (or acidity). Bread has a pH of about 5.3 - 5.8 which means it is slightly acid. This also helps keep it safe to eat on the shelf." One way to estimate how quickly bread will mold would be to look at its water content. For example the percent of water in several breads is: Navaho fry bread 26%, banana bread 29%, toasted white bread 30%, plain white bread 36%, Oat bran bread 44% and canned Boston brown bread 47%. This is the quickest way your going to get mold Anything that is wet and is in a warm spot will make mold. Moist bread, sponge and thing that can hold water will make mold. Place the thing in a plastic bag, close it so no air can get in or out. Place the bag in a sunny window for a couple of days and it should start to grow mold. Try several types of objects so you will get several types of mold. or Find a homeless and ask if you can scrape them.

It depends on the type of bread. Most packaged breads have lots of preservatives in them and will keep for a couple weeks. If you want to grow mold fast, get some fresh bread from the grocery store bakery without preservatives in it. It will mold much quicker.

Depends on the type of bread, some mold faster than others. Are you doing an experiment?

It depends on the type of bread and where you store it, If it's warm in that area it will grow mold faster, and if it's cold it would be awhile.

It depends on the temperature, the humidity, and the mold count

When you want the bread to use for sandwiches, etc. it gets moldy too soon.
If you have to do an experiment for school, etc. it doesn't get moldy on time.
