Wash and rinse all veggies well before slicing or chopping. Place in a large stockpot or slow cooker. Add the ginger, turmeric, garlic cloves, bay leaves, wakame, coconut aminos, and any other herbs or spices. Cover with the water.
If using the stove and a stockpot, bring to a boil, and then lower the heat to a simmer. Cover pot and cook for 2–3 hours. If using a slow cooker, cover with lid and turn on to HIGH for 6–8 hours or overnight. (Note: I don't like using LOW heat when using my slow cooker for broth. It should be simmering, and I've only had that happen when I've used HIGH heat.)
With a slotted spoon, remove the solids from the pot or slow cooker. Set a large fine mesh strainer over a big bowl or another pot and strain the broth. If not using immediately, transfer the broth to jars or other airtight containers. Let cool slightly before placing in fridge or freezer. Broth should keep well for about 3–5 days in the fridge and several months in the freezer.
This broth has very little salt (except for the aminos), so add salt to taste according to how it will be used in recipes.
