i dont think scientists make weed cookies too, often... but they should.
im not saying that butter steeped overnight loses all potency, but you are losing thc and you are losing (any chance of good) flavor.
I also do two hours on high out of the four hrs, makes a huge difference.
but.... if its not broken, don't fix it. if your friends love the recipe, then you found your own niche and you should stay with what works for you. in my personal exp 2 high/2 low just came out better. loving the discussion colts
