Never tried a Douglas fir, but we grew about 40 acres of them when I was growing up. tree farmers. I'll have to try that!Excellent job! Definitely some tasty looking flower in the pics.
I have always liked to press my kief into rosin, it always makes for a nice gooie return!
You ever roll a Douglas Furr joint? Roll a log of bubble hash n put it in some flower in a joint then coat the outside of the J with rosin then dip that in the kief. Looks like a furry joint. They smoke like a locomotive when they burn! I'm looking forward to seeing how those testers turn out for ya!
