ReUseing

I plan to germinate some seeds in wet paper towel, and plant in a mixture of promix, perlite, and some vermiculite in a 2 gallon pot. Can this stuff be used again for new seedings or clones? Would like to know all the answers to my questions before i even start. Getting close to being a newbe.
Thanks for any info.
