I've always personally been a "one and your done" type guy when it comes to running my material, especially because I have more than enough material for myself. You mention processing the same material 7 times over? Really? Is it worth it? Do you reuse the water? Or just the material with fresh water? Are you hand mixing or using a bubblenow? Do you change your mixing times? Any information would help. I have just heard YBG doing multiple runs with same material as well as others. Wondering if it's worth the efforts. thanks.
