@ringo @kekkerel Another thing to consider is growing your own mushrooms. In particular, lion's mane, turkey tail, and reishi mushrooms have some potent properties discussed in the Lost Book (lion's mane for brain/nerve function, turkey tail for cancer and immune system support, reishi for stress control).

You can search for starter kits that grow inside, in indirect light, and you basically just have to mist them each morning and then harvest after a few weeks.
