Sure. The older the spore the more water it loses to the environment. Under the microscope you can see that the sides suck in as it loses water. The more water it loses the less likely it is to germinate. But the process is reversable (with exceptions). So typically spores are placed in sterile water for 12 to 24 hours to re-hydrate. Cultivators that use syringes just load a syringe and let it sit overnight.I collect 5 prints worth of spores in a sterilized 40 ml jar. The jar has a small hole in its lid. The hole has self-sealing latex covering it. When it comes time to innoculate...I sterilize water in another container and suck up some of this water into my syringe and inject it into the spore jar. Suck the spore water up and inject it into the original container of sterile water. This spore water is what is used to charge syringes. Using this method you are automatically hydrating your spores as long as you allow them to sit. Older spores may take longer and younger ones less, but 24 hours has proven to work well.
