Any advice on cold water extractions? So I just ordered some Hawaiian Baby Woodrose from Shaman Gardens and am planning on trying the cold water method 1 as listed on the sidebar. It all seems simple enough but I've heard of these not working for some people and I was wondering if there were any common mistakes I should make a note to avoid? Does exposure to light not matter after the 4 hours in the fridge is up? Will a coffee filter work as a sieve? Just little stuff like that I'm afraid to fuck up.
