I have now experimented with two methods of solar decarboxylization. One involved putting the cannabis inside of a folded-up piece of printer paper, then placing it inside a foil coffee bag and letting it sit on my brick patio in the sun, this worked but I wondered what the neighbors would think (I have a lot of busy body old ladies for neighbors). The second method was to place several buds in a small metal box that originally contained Godiva (yum) chocolate pieces. The lid is quite tight and it is dark brown in color, so it absorbs heat well. I set the metal box on the dash of my car while I am at work, making sure to park in such a manner that it to get as much sun as possible. On a 90-degree day my car smells wonderful at the end of the day and the cannabis has changed color from a dark, commercial green color to a dark brown shade with a pleasant and distinctively non green bouquet. This herb smokes a little harsh but works well. About two grams are now soaking in one ounce of Amaretto. All in the name of science (and well maybe getting high)
