Update: just added the bottom pic, got them nice pots, soil, and 50/50 perlite. No water yet waiting a month, correct me if I should water sooner please. I think I may have over watered my pachanot, it has gone a bit soft and lighter shade, I repotted with the new soil you see in the bottom pic, hoping for the best. I don't water my penis cactus much, as it's bridgessi, and have no problems there. From pics I've seen it looks like these guys really are juuls giants, very fat, extremely small and sunken in spikes, simmilar to pachanoi but distinctively different. Please let me know any thoughts. I would love to learn as much as I can
