Hydei take longer than the smaller Melanogaster's...but tell us what is in the container...do you see little maggot like things moving around ranging from tiny to larger ones? What about little brown things stuck to the side? If you can tell that those little brown things are filled with something, those should hatch out to FF. Also, FF like it cooler, so maybe keep it in a cool place in your home. I keep mine indoors at room temperature which is about 73 degrees.
I'm sure someone can give you more technical info...but mine is all laymans terms.
