When you are nearing the end of flower and wondering when to take a plant/table a quick dry/smoke to test high profile is often a good way to tell if you'll like the table. Essentially by correlating trichome appearance to high performance is informative. (I really hope this makes sense because I'm smoking my most recent table). I wouldn't waste the time on extracting because I can dismiss a harsh smoke, but if you can't extracting would make sense! Interesting thought, thanks.if you really MUST sample make small batch of QWISO or QWET , least potency lost and can be done with fresh flower
