I make canna coconut oil with my old buds. I try to keep some kind of coffee cake or brownies handy for when I can't smoke. But it's a good thing I keep some of the old shit on hand. After last year's rot fest, I'm getting kind of low. {For this time of year, anyway}
I did have a couple of plants early flower last year, and never reveg. I need to get some of those seeds out and see if history will repeat itself. I chopped those two in late July/early August. That would be a huge stress relief to have fresh bud in the summertime.
