The reason that I asked about the timer being digital is as I found out with one years ago that most are sealed and once the internal battery dies for the display you then having to throw it away. Plus as far as making canna butter I want to tell you from experience that you are going to be disappointed with the taste and buzz using that very premature plant. To make a good quality butter just start saving your dried sugar trim to infuse with. Using dried trim and buds the butter will absorb way less of the chlorophyll giving it a lot cleaner taste, color, and high. We infuse coconut oil for cooking having almost no taste of its own. It gives you a lot more options with recipes. Two of my favorites are deep fried canna fries, and fried Zucchini . We either add canna coconut oil or bubble hash to the fryer. The bubble hash is a way more intense buzz then the coconut oil when using in any dish. Also it has little affect on the taste of what your cooking.
