What is the optimum time for cooking cannabutter using a pan of weed and butter, which is placed in a pan of boiling water, without touching the bottom of that pan, therefore making sure it is not exposed to temperatures over 100 degrees centigrade. I've had good results using this method and cooking for about 6 hours once before.

I've heard that the optimal time is 23 hours for the water mixed with butter method, tbh it doesn't really matter to me how long I have to cook it to get the most out of it, since I want to make it in advance. Could even cook it all day then start cooking again the next day lol. I've heard that thc gets destroyed if cooked for too long though.
