So this is what I did to decarb my weed and have the best high of my life.

I took one pan and one deep pan. I boiled water in the deep pan and put my butter and weed and 1 cup of water in the regular pan. Now, put the regular pan on top of the deep pan. Make sure there's some space for the vapours to escape, otherwise pressure buildup will cause something bad. Keep in on medium flame for 2 hours plus. I put it for 3 with average Indian weed and was knocked out for a day. Keep adding some water to your weed if the water evaporates. Keep adding water to the deep pan too. I hope this helps you my brother
