Think I should make an updated tutorial on how to ferment substrate? Think I need to make a more up to date one. I have new techniques/methods I found through trial and error. Already have a video stored in drafts on my iPhone, just waiting to get the finish products and give some extra tips. I will list all supplies needed and not use ratios so it's easier for everyone to follow. Let me know what you guys think. Below is the older video I made.
