Oh.. Something else...
It's a question...
What makes bud taste like straight up soil? I smoked some with one of my buddies yesterday, And it had a taste like the blunt was half bud, and half potting soil. The shit looked looked great... Bright green with purple patches, and a heavy coating of trichs... But the taste though...that was some "Man...I'll just roll one out of my leafy ass bag of half cured GG4, Because it's smooth as glass in comparison" shit. Heavy stone, though. Made fishing for hybrid striped bass a major task...
It could be the strain - some tase more earthy than others.
It could be mildew
If it smells bad .. it could be mold.
