Drying a screen once it's been coated is much more critical than most think. After you are done degreasing and have coated your screen you need to place it to dry horizontally with the print side down. The reason that drying a screen is so important is because it is going to determine the outcome of how your emulsion cures which affects it breaking down prematurely on the press. Gravity can help you out by making a thicker stencil for your design.
So let's talk about a couple different ways you can dry a screen.
Commercial drying cabinets - These should max out at around 100 degrees Fahrenheit. The ideal drying temperature for your coated screen is between 85-95 degrees Fahrenheit with low humidity. With this being said the majority of screen shops do not have fancy drying cabinets with temperature control so lets move to option 2.
DIY Cabinet - Most printers are going to have a screen rack with some sort of cover, or you might have built a DIY cabinet to keep it nice, dark and free of dust. Your screens are going to air dry naturally at room temperature, which isn’t a bad thing, it's just going to take longer than a commercial drying cabinet. A nice cheap trick is to buy a small inexpensive fan that you can fit in your cabinet to get some sort of air flow circulating within your screen rack or cabinet.
Something that new printers don’t consider is that your humid climate in Florida is going to take your screen longer to dry than in New Mexico’s dry air.
